I remembered now that we should check workspace inheritance for this lint, as well as for redundant_readme. Do we want to address it in this PR, or we merge this and fix them in follow-up?

Let's merge and I'll handle it in a follow up just so this doesn't sit rotting

### What does this PR try to resolve? This is a follow up to #16561 (comment) ### How to test and review this PR? This does not intend to be perfect, just a step. In particular, we need to decide the exact behavior of these lints in several scenarios - When inheriting `package.readme`, it can only redundant in one location, is it worth linting when inheriting? - When inheriting `package.homepage`, should we be applying a workspace lint? Technically, there can be odd combinations where the current implementation wouldn't fire but it would.
