NODE-4108 Description

What problem are you facing?

The Node.js Driver types for session.withTransaction are completely wrong and misleading

What driver and relevant dependency versions are you using?

`mongodb@4.4.1` 

Steps to reproduce?

Look at the code in mongodb.d.ts. It says that the return type depends on the input to the withTransaction function. But in runtime, the function always returns :

{ "ok": 1,"$clusterTime": { "clusterTime": { "$timestamp": "7077570972357754881" }, "signature": { "hash": "AAAAAAAAAAAAAAAAAAAAAAAAAAA=", "keyId": 0 } }, "operationTime": { "$timestamp": "7077570972357754881" } }

 I don't know if this is a bug in `withTransaction` - or a type issue - but it needs to be fixed soon. I have tried to raise attention about this for almost a year in the community 😅
