Which issue does this PR close?

Rationale for this change

While reviewing #17195 from @mbutrovich and other recent PRs related to type signatures, I believe the current behavior and implications of TypeSignatures is not clear; I think it is especially confusing to understand what "supported" means

Thus I would like to improve the docs to help

What changes are included in this PR?

Improve the documentation for type signatures in general to explain what they mean and the implications better.

Are these changes tested?

By CI

Are there any user-facing changes?

Some better docs and examples
