fix(eslint-plugin): [no-unsafe-return] allow returning anything if explicitly returning any

[Josh-Cena]

PR Checklist

• Addresses an existing open issue: fixes [no-unsafe-return] does not allow return any[] when function is typed as any #3549
• That issue was marked as accepting prs
• Steps in Contributing were taken

Overview

I'm not sure if we should handle the following case: const x: () => any = () => [] as any[];

Overall the docs does not make it clear which cases are exempted, so I guess we have some room for interpretation.

👍 very reasonable!

[JoshuaKGoldberg]

[Testing] Could you add a test for unknown too?

some room for interpretation.

Yeah I think this is fine as-is for now. If folks really give solid use-cases for the more complex ones we can always look into adding more complexity.
