Investigate NODE-4423 - Type Regressions in 4.8

NODE-4423 Description

What problem are you facing?

It's great with Type support for updates, but it comes with at least two regressions breaking a lot of our codebase. I'm omitting _id when creating the collection type (see screenshots) - as I believe was the recommendation before.

1. _id is not allowed in neither $set or $setOnInsert. It is still allowed for queries, so I'm pretty sure it's not an error in our types.
2. Setting sub-documents doesn't seem to be work either.

This gives a lot of errors - especially since type errors on the queries/updates somehow breaks the entire type resolve chain (any subsequent code won't even recognise it's dealing with a promise anymore).

What driver and relevant dependency versions are you using?

Node.js Mongo Driver 4.8 and TypeScript 4.7.4

Steps to reproduce?

Set up the types as per the screenshots.
