Chore: split rubocop from bulk dependabot

[colinbruce]

What

The first version did not work as the documentation suggested, so this is V2
The rubocop changes block so many other gems, we agreed to try splitting liek this and see if it allows us to work on rubocop fixes without delaying other gems

Checklist

Before you ask people to review this PR:

• Tests and rubocop should be passing: bundle exec rake
• Github should not be reporting conflicts; you should have recently run git rebase main.
• The standards in the Git Workflow document on Confluence should be followed
• There should be no unnecessary whitespace changes. These make diffs harder to read and conflicts more likely.
• The PR description should say what you changed and why, with a link to the JIRA story.
• You should have looked at the diff against main and ensured that nothing unexpected is included in your changes.
• You should have checked that the commit messages say why the change was made.
