How can I solve this CI failure?

Thanks for looking into this.

Are we sure that ronn-ng is that alternative man page generator that we want to use here? @Bo98 I see that you self-assigned the original issue. Is this what you had in mind?

Also, we don't want to vendor dev dependencies like this. That's why the check is failing. For the man page gems, we specifically download them whenever brew generate-man-completions is run in the following snippet which installs the :man group of gems in the gemfile. That's why ronn is currently listed as both optional and not required.

ronn-ng has the cloest functionality to ronn, and this can serve as a temporary solution while @Bo98 is figuring out what's going on and bring up a better solution.

Thanks for your first contribution!

It looks like ronn-ng has nokogiri as a transitive dependency. However, I noticed a note in the Gemfile that nokogiri is a disallowed dependency. (Introduced in this PR, cc @samford)
