text: Title: make typecheck failing
  Body: ### Initial Checks
  
  - [X] I confirm that I'm using Pydantic V2
  
  ### Description
  
  I'm trying to commit a change and the pre-commit hook make typecheck is failing on various bits of v1 code. I reverted my changes and ran the check - same result, so not sure how others are managing to commit!
  
  There are 144 errors, so I'll spare everyone the whole output, but a couple of samples are below. I've checked that I've got the latest versions of all dependencies, such as mypy.
