wouldn't it be better to split the changes to make the changes merge more easily then changing everything at once?

Hi @auvipy Thank you for your patience. It's already so big it'll take too much time to split. I need a couple of free weekends to finish this up: update build config, update linters consigs, update docs, and that's it. The code is already passing all the tests locally, so if you want to, you can check it by installing from the latest commit.

Since these changes were included as part of the major changes in https://github.com/mts-ai/FastAPI-JSONAPI/pull/97, this PR is closed. The update was applied not only to the Pydantic library but also included version upgrades for SQLAlchemy and FastAPI. Performance has more than doubled; for example, with 50 users, the average response time decreased from 302 ms to 138 ms. Thank you.
