Non blocker: Is there a way we could read these from a peer dependency of @primer/react?

Feels awkward to have to keep syncing between primer/react and eslint-plugin-primer-react

I would love if we could do this! I'm not entirely sure how though, unless we move this mapping into primer/react itself. Wondering if there's an alternative way to go about this.

Edit: Will loop back to this! I think we could potentially add something here, but will require coordination from @primer/react
