patch pydantic v1.10.9 conflict with py3.12

[luca-knaack-webcom]

There are errors in pipelines that run the testing configuration python=3.12 and pydantic=1.10.9. The error is something like:

| ________________ ERROR collecting tests/parser/test_openapi.py _________________
| tests/parser/test_openapi.py:10: in <module>

|     return cast(Any, type_)._evaluate(globalns, localns, set())
| E   TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'

and results in a massive amount of errors like:

ERROR tests/test_format.py - TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'

To patch the missing recursive_guard keyword argument, I created a pydantic_patch file that gets imported early in datamodel_code_generator.__init__.py and that patches the underlying evaluate_forwardref function.

This PR is should fix most of the broken tests in the pipelines for pull requests #2013, #2009 and #2008.

While there is still one failing pipeline, this is the godspeed-benchmark, that isn't able to run on any PR's pipeline.

@koxudaxi, I had to change the codspeed-benchmark action to always install the dependencies, as the cached virtual environment seems to lack the pytest-xdist package. Once the cache is refreshed, the commented out line could be reintroduced.

@cclauss Thank you for spending so much time on this difficult issue. I was commenting on the code, but I am concerned about the support for other versions, but I don't think it is a problem now, so I will merge it. Thank you very much.

For performance reasons, you may also want to include a version check on the pydantic side.
