- Implemented logic to disable GPG commit signing in repositories to prevent signature errors in automated workflows.
- Upgraded dependencies in `go.mod` and `go.sum` to align with the latest `github.com/go-git/go-git/v6` alpha releases.
- Added unit tests to verify commit signing is properly disabled in repositories.
Closes: #4341
- Updated `maybeRunGC` to accept `repoDir` instead of `repo`.
