Add Github action that watches when we change dependencies
Github has a feature where you can add a CODEOWNERS file and it will require a review from people or teams you specify, any time certain files have changed.
Foreman uses this to require reviews from @theforeman/packaging any time package.json has changed (or, any other files that would break packaging). See https://github.com/theforeman/foreman/blob/develop/.github/CODEOWNERS#L4
However, Katello can't use this because "The people you choose as code owners must have write permissions for the repository."
As an alternate solution, we should look into a Github action for Katello that comments on PR's-- maybe tag packaging if the PR changes one of those files.
