generate_self_schema.py incompatible with Python 3.13.0b1
Python 3.13.0b1 (initially python/cpython#118009 but there have been several follow ups) changed the signature of ForwardRef._evaluate so it is now _evaluate(globalns, localns, type_params=_sentinel, *, recursive_guard)
generate_self_schema.py calls this function as follows (with a fallback):
https://github.com/pydantic/pydantic-core/blob/aed68446d61594ead7920cff3dcd478093626c8e/generate_self_schema.py#L191-L196
and therefore fails on both branches with TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'
Locally I changed set() to recursive_guard=set() and it builds fine (with the UNSAFE_PYO3_SKIP_VERSION_CHECK environment variable).

We'll be testing on 3.13 very soon, just waiting to get this in PyO3 first https://github.com/PyO3/pyo3/pull/4184
When we changed the version explicitly in pipfile, pydantic from 1.10.15 to 1.10.16 which solved the unit test step failure issue in github Actions. Upgraded python runtime from 3.8 to 3.12 then we got the error in GitHUb actions unit test step "TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'"
