Update dependency pydantic to v2.13.4 (#80)

* Update dependency pydantic to v2.13.4

* Pin pydantic to 2.12.x for PyPy 3.10 compat

pydantic 2.13 bumps PyO3 to 0.28 via pydantic-core, which drops

PyPy 3.10 support. Revert the requirements.latest.txt bump and add a

Renovate rule mirroring the existing jiter <0.12 pin, so this won't

be re-proposed until PyPy 3.10 is removed from the matrix.
