Update CI workflow

[mishina2228]

• Bump actions/checkout from v1 to v3
• Enable bundler-cache to cache gem dependencies
  • I had to change .rubocop.yml to suppress the following error:

    Unable to find gem panolint; is the gem installed? Gem::MissingSpecError
    

  • refs: RuboCop pulls in .rubocop.yml files from vendor directories rubocop/rubocop#9832
• Add Ruby 3.2 to the CI matrix
• Fix the RuboCop error in GitHub Actions

If I remember correctly, there was a reason why the bundler cache was not used. Should be a comment on a pull request similar to this one.

By default these actions install gems inside the project root which messes up RuboCop check because it check all ruby files in the project root. At least that's how I remember it. Maybe things have changed since then or I might've dome something wrong. In any case CI is clearly misconfigured…

Yeah, that's why I had to change .rubocop.yml to make RuboCop ignore the ruby files in gem dependencies.
I've edited the description to mention it.

Looks like this might be an upstream issue, found rubocop/rubocop#9325 which I think describes it. Another fix for this seems to be this in .rubocop.yml:

inherit_mode:
  merge:
    - Exclude

I see that the changes in this PR are already in the master branch.
I also understand about the policy of not using bundler-cache from this comment, so I'm closing this PR.
