Add export functionality for scan results

[mgoldver]

Add an export feature that allows users to save vulnerability scan results in one or more of the following formats:

JSON - For programmatic processing and integration
CSV - For spreadsheet analysis and reporting
HTML - For human-readable reports
SARIF - Standard format for security analysis tools (enables integration with other tools)

Suggested Implementation

• Add an "Export" button or context menu option in the JFrog tool window
• Allow users to choose export format and location
• Include all relevant information:
  • Vulnerability details (CVE, severity, description)
  • Affected components and versions
  • Remediation recommendations
  • Scan timestamp
  • Project information

Use Cases

• Security teams need to track vulnerabilities across multiple projects
• Compliance requirements demand audit trails of security scans
• Integration with automated reporting systems
• Historical tracking of vulnerability remediation

Additional Context
This feature would significantly improve the plugin's utility for enterprise environments and align it with other security scanning tools that provide export capabilities.
