Drop support for Ruby 3.0, and adopt Rubycritic changes for Ruby 3.1.

- Drop support for Ruby 3.0.
- Update Rubycritic config to target Ruby 3.1. Apply all safe autocorrections except for Style/HashSyntax.
- Set Rubycritic's Style/HashSyntax EnforcedShorthandSyntax to 'never', which keeps the old style in place (and consistent) until we decide to convert.
- Add Ruby 3.3 to the test matrix and Drop Ruby 3.0 (which largely includes the changes in whitesmith#488, so we'll need to rebase if that's landed when we do something with this)

Bump minitest, mocha, rubocop dependencies
