Add information about class in error message of schema generation

[Czaki]

Change Summary

Finally, the last of my dependency reached pydantic 2 compatibility, so I could start migrating my package. I meet an error that requires using a debugger to understand where is a problem as I cannot find which class is responsible for the problem. In this PR I add information about class that have __modify_schema__ and do not have __get_pydantic_json_schema__

Left a few quick notes. Looks good, assuming you fix the linting errors as well. Thanks a bunch!

@Czaki,

You should be able to run make and use pre-commit logic to help you with the linting errors 👍

[Czaki]

I think that I have done it.
I do not know why your pre-commit configuration do not fix formatting and does not print what needs to be fixed.

@Czaki,

Looks like you fixed the linting, but your test is failing

I see, but your workflow is totally different from this one that I’m familiar with, and it takes me longer time to identify how to test things locally.
