feat: migrate website from Hugo to Docusaurus

[KushguptaPST]

Hi team,

This PR migrates the Volcano website from Hugo to Docusaurus. The goal is to make our documentation easier to maintain, customize, and contribute to, while taking advantage of Docusaurus’ React-based architecture, MDX support, and plugin ecosystem.

fixes #455

What’s changed
Hugo → Docusaurus

Initialized a new Docusaurus (v3.x) project.

Removed legacy Hugo setup.

Original Hugo content was backed up locally during migration (hugo_backup/) but is excluded from the repo to keep things clean.

Content migration
.Documentation moved from content/en/docs → docs/
.Blog posts moved from content/en/blog → blog/
.Static assets (images, logos, etc.) moved to static/

MDX compatibility fixes
.To ensure a clean Docusaurus build, several Hugo-specific and legacy Markdown issues were resolved:
.Replaced Hugo shortcodes with standard Markdown/MDX syntax.
.Fixed invalid or legacy HTML (unclosed tags, unquoted attributes, improper nesting).
.Converted inline HTML styles to MDX-compatible JSX where needed.
.Escaped mathematical operators (<, <=) that conflicted with the MDX parser.

Verification
.The site builds successfully with npm run build.
.You can preview locally using npm start.

Notes:
.This PR focuses on stabilizing the English content first. Other languages (e.g., Chinese) can be handled in a follow-up.
.There are some non-blocking warnings (broken links, git history) in the build output, but they do not affect the build.

Summary of Changes

Hello @KushguptaPST, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents a significant architectural shift for the project's website, transitioning from a Hugo-based static site to a Docusaurus-powered platform. This migration aims to enhance the overall developer experience for maintaining and contributing to the documentation and blog, leveraging Docusaurus's modern features like React components and MDX support for improved flexibility and scalability.

Highlights

• Website Platform Migration: The website has been fully migrated from the Hugo static site generator to Docusaurus v3.x, involving a complete overhaul of the underlying framework and content management system.
• Content Restructuring and Compatibility: Existing documentation and blog posts have been moved to Docusaurus-standard directories (e.g., 'content/en/blog' to 'blog/') and adapted for MDX compatibility, including replacing Hugo shortcodes with standard Markdown/MDX syntax, fixing invalid HTML, and escaping problematic characters.
• Removal of Legacy Assets: All Hugo-specific configuration files, custom CSS, JavaScript, and other related assets have been removed, streamlining the repository and eliminating outdated dependencies.
• Updated Development Workflow: The project's README.md has been updated with new instructions for installing, developing, and building the website using Docusaurus's npm-based commands.

Code Review

This pull request represents a significant and well-executed migration of the Volcano website from Hugo to Docusaurus. The changes correctly handle the transition of content, including converting Hugo-specific shortcodes to MDX-compatible syntax and updating project configuration files like .gitignore and README.md.

My review focuses on a few key areas for improvement:

• Project Governance Files: The removal of the LICENSE and CODE_OF_CONDUCT.md files is a major concern that needs to be addressed to maintain legal compliance and community health.
• HTML Best Practices: Several markdown files contain obsolete HTML tags (<center>, <font>) that should be replaced with modern CSS-based styling for better maintainability and standards compliance.
• Content Parity: As noted in the PR description, the Chinese documentation has been removed. While this is planned for a follow-up, it's a significant temporary regression in content availability.

Overall, this is a great step forward for the project's documentation platform. Addressing the identified issues will help ensure the new site is robust, maintainable, and compliant.

[gemini-code-assist]

The LICENSE file has been removed. This is a critical file for any open-source project. It seems it was not added back as part of the Docusaurus migration. Please ensure an Apache 2.0 license file is present at the root of the repository to maintain legal compliance.

[gemini-code-assist]

The CODE_OF_CONDUCT.md file was removed. A Code of Conduct is essential for fostering a healthy and welcoming community. Please add it back, perhaps in a location that Docusaurus recognizes, or create a new one based on a standard template like the Contributor Covenant.

[gemini-code-assist]

The <center> tag is obsolete in HTML5 and not recommended for styling. For centering content, please use CSS styling, for example by wrapping the content in a <div> with an inline style. This will improve maintainability and adhere to modern web standards. This issue also appears in other migrated blog posts.

Suggested change

	<center> <img src="/kubecon/2024-paris.png" /></center>
	<div style={{textAlign: 'center'}}><img src="/kubecon/2024-paris.png" /></div>

[gemini-code-assist]

The <font> tag is obsolete in HTML5 and should be avoided for styling. Please use modern CSS approaches, such as <span> elements with inline styles or CSS classes. This improves maintainability and follows web standards. This tag is used multiple times in this file.

Suggested change

	<font face="Arial" size="4"> As artificial intelligence (AI) technologies advance and large language models (LLMs) grow more popular, the demand for AI compute has been booming. This has generated huge demand for high-performance scheduling for the AI and for hardware like AI chips.</font>
