Pass 2 of making lazy imports a reality on 3.15+ (Pass 1: #5231).

Seems like AI was able to reduce the import time which I couldn't quite do on my first pass on this a few months ago:

Import Before After
telegram 126.8 ms 26.3 ms
telegram.ext 142.8 ms 26.4 ms

Also made it add a pre-commit hook for maintaining the __lazy_imports__: It adds missing entries, removes stale ones, sorts and deduplicates both lists.

Sorry, something went wrong.

Uh oh!
