Update golangci-lint to use v1.8.0

[kalexmills]

I've opened a PR upstream to integrate the recent changes: golangci/golangci-lint#5707

I realized after I'd already written and tested the PR that golangci-lint policy requires the author of the linter to make all changes involving their linter.

@jgautheron I'm leaving this here so you have the diff when it comes time to do a bump upstream.

The golangci-lint policy doesn't require the author of a linter to make PRs to update the linter.

We handle that with the dependabot: golangci/golangci-lint#5707 (comment)

[kalexmills]

Thanks for the clarification. I guess I got confused about the policy because the documentation on the website says:

No pull requests to update a linter will be accepted unless you are the author of the linter and specific changes are required

A similar message is included in the PR template.

Note that 1.8.0 has a bug: #37

This issue can be closed: golangci/golangci-lint#5712

That was lightning fast, thanks @ldez!
