/kind documentation

• What this PR does / why we need it:

This PR adds comprehensive documentation for the HyperJob concept to the Volcano website in both English and Chinese. HyperJob is a high-level multi-cluster scheduling abstraction built on top of Volcano Job that enables:

• Automatic job splitting across multiple Kubernetes clusters
• Unified status management for multi-cluster workloads
• Simplified multi-cluster AI/ML job orchestration
• Better resource utilization across heterogeneous clusters

Additionally, cross-reference links have been added to the existing Multi-Cluster Scheduling documentation to improve discoverability.

Summary of Changes

Hello @codeEvolveZenith345, 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 significantly enhances the Volcano project's documentation by introducing the HyperJob concept. HyperJob provides a crucial high-level abstraction for managing large-scale AI/ML workloads across multiple Kubernetes clusters, simplifying complex distributed job orchestration. It aims to improve resource utilization and provide a unified control plane for jobs that span heterogeneous and geographically dispersed environments, thereby making multi-cluster AI job scheduling more accessible and efficient.

Highlights

• New HyperJob Documentation: Introduced comprehensive documentation for the HyperJob concept in both English and Chinese, detailing its purpose, features, and usage within the Volcano ecosystem.
• Multi-Cluster AI Workload Orchestration: HyperJob is presented as a high-level abstraction for multi-cluster AI workloads, enabling automatic job splitting, unified status management, and simplified orchestration across multiple Kubernetes clusters.
• Key Features and Use Cases: The documentation outlines HyperJob's core capabilities such as automatic job splitting, unified status management, and high-level scheduling, along with typical use cases like multi-cluster LLM training and heterogeneous resource scheduling.
• Comparison with Volcano Job: A clear distinction is made between HyperJob and standard Volcano Job, highlighting when to use each based on single-cluster vs. multi-cluster requirements and job splitting needs.
• Cross-Referencing: Existing multi-cluster scheduling documentation (both English and Chinese) has been updated to include cross-reference links to the new HyperJob concept, improving discoverability.
