[CI] Pin to a specific tag for the golangci-lint image

Summary

As found in #966 (closed), a recent update to the version of golangci-lint in the shared CI image brought in new checks. These new checks caused a failure in one of our branch release pipelines.

It was requested to tag the specific version of golangci-lint so we can avoid these failures in the future.

Acceptance criteria

• Version of golangci-lint used in CI can be pinned (and updated intentionally when ready)
