Add GitHub Actions workflow for Go docs update on tagged releases

- Introduced `godocs.yml` workflow to automate Go documentation updates when tags matching `vX.X.X` are pushed.
- Verify tags are on the main branch before processing.
- Use `actions/setup-go` to set up Go environment for the workflow.
- Added Go proxy ping step to ensure update is queued.
