Fix linter warnings (#3854)

- **PR Description**

Fix some linter warnings that I keep getting locally because I'm running
a newer version of golangci-lint than the pinned version we use on CI.

Also, update the pinned version in CI to 1.60 so that we are in sync
again.

Finally, upgrade the golangci-lint-action version to the latest,
although I'm not sure what difference this makes. The linting step runs
faster now, maybe because of better caching -- I noticed that
previously, loading and saving the cache took a very long time, which
often made the lint step the slowest of all.
