"payload-types.ts" in website template always outdated

[bormm]

Describe the Bug

This is not a regular runtime bug, but I noticed in previous versions and now again in 3.5.0 that the "payload-types.ts" is changed without changing anything in the code. I reproduced this now with a fresh payload app.
Previous fields in meta was removed without having changed something myself:

With 3.5.0 its 46 changes, I think all are string to number, happening:

I think that's a process workflow issue: I guess people are making code changes in collections and so one, but then are not rerunning the "payload generate:types" process. As the changes often do not cause a runtime issue by the nature of the "flexible types handling", nobody is noticing that there is a drift.

My recommendation is that the "run payload generate:types" is put into the PR process and either it fails when there is a change needed, or it applies change automatically and if everything runs is merged.

Why we should care: The template should be consistent and correct from the beginning. Otherwise it will happen that developers waste time analysing why the types are changes to much after running "payload generate:types", only to find out it wasn't anything they have done in the code.
