Minor nit: Can you split the commit into two, one for the golangcli-lint version update and another for Golang's?

Same applies to #836

Can you split the commit into two, one for the golangcli-lint version update and another for Golang's?

Yes, I agree. But I won't insist on it for such minor changes, and we won't update the changelog for either change.

Per #837 (comment), this LGTM. Thanks, Agni.

Quick question, @ahrtr: did you manually approve the workflows for the pull request? I see it skipped the ok-to-test label, but I'm unsure why the tests ran.
