MCP google/go-github@V79 update

[stephenotalora]

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

This PR updates our google/go-github dependency from v77 to v79 to incorporate the latest ProjectsV2 fixes released in v79.0.0 which includes the following bug fixes:

• Upstream corrected the field-selection and unmarshalling behavior for several ProjectsV2 GET calls.
• These fixes ensure that item fields, field values, and metadata returned from the API now decode reliably into the corresponding go-github structs.
• The Field property in UpdateProjectItemOptions has changed from a single value to: []*ProjectV2FieldUpdate

This aligns the client with the actual API contracts. As part of the update I have also taken care of:

• Updating all import paths to github.com/google/go-github/v79.
  -go.mod and go.sum have been refreshed to pull in the corrected ProjectsV2 models.
• Any internal logic interacting with UpdateProjectItemOptions.Field has been updated or validated to ensure compatibility with the new slice-based type.
• Projects-related unmarshalling inconsistencies we previously hit (e.g., empty or incorrectly typed field values on GET responses) should now be resolved.

Why this upgrade matters

The upstream fixes directly address decoding issues seen when interacting with ProjectsV2 APIs. Moving to v79 ensures that the MCP server correctly parses the Project item payloads returned from GitHub and supports the updated mutation format for field updates.

Local Testing

The update has been tested against projects APIs already integrated with google/go-github, for reference see screenshots as part of this PR.
