Subject: [PATCH] Drop Ruby 2.6 support

Follow up https://github.com/rubocop/rubocop/pull/11791.

This PR drops Ruby 2.6 support. And JRuby has been dropped from the CI matrix because
no JRuby-specific issues have been found and prevents the following build error:

```console
#!/bin/bash -eo pipefail
bundle install

This does not mean no support for JRuby. RuboCop Rails will continue to support JRuby 9.4+.
