Updates github-mcp-server to go-github/v76

Towards: https://github.com/github/memex/issues/20995

Summary

The primary objective of this pull request is to update github-mcp-server to use the latest version of Google's go-github library (v76) where ProjectsService is first introduced. This upgrade aligns the server with recent GitHub API changes and leverages enhancements and newly introduced functionality available in go-github/v76@latest.

While best efforts were made to adopt the existing ProjectsV2 APIs from upstream, not all components have been migrated yet. Further updates are pending the merge of google/go-github#3733, which introduces additional APIs required for full integration. Once merged, subsequent iterations will continue updating the MCP server to ensure complete feature parity with the upstream library.

Details

For easier review, I recommend going through this PR in commit order:

• Dependency Update:

  • Upgrades go-github from v74 to v76 across the codebase to reflect the latest API surface and deprecations.
  • Adjusts internal calls where needed to align with breaking changes and updated interfaces introduced in v76.
    (Commit: ee90778)

• License Updates:

  • Refreshes license files to ensure compliance and correctness following the dependency upgrade.
    (Commit: a73d2b4)

• Code Refactoring:

  • Refactors ListProjects and GetProject to use the official ProjectsService from google/go-github.
    (Commits: ac0df34 and 5599e22)
  • These updates replace custom or outdated implementations with the official client methods, aligning the server with upstream API conventions and improving long-term maintainability.

Trade-offs and Considerations

• Some internal interfaces and usages were updated to accommodate breaking changes in go-github/v76.
• The upgrade may introduce minor behavioral differences due to upstream library changes; specially those changes outside of our domain (in Commit: ee90778).
• The google/go-github library introduces additional APIs in Add Endpoints For Project Items google/go-github#3733. While existing APIs have been adopted where possible, not all functionality has been migrated to v76 yet. Certain APIs remain unavailable upstream, so refactoring projects.go for partial functionality would not be practical at this stage.

Testing

Run the MCP server locally and ensured the agent was hitting the updated tools using `google/go-github` APIs
