pybind11 v2.12.0

[agriyakhetarpal]

Description

Bump to pybind11 v2.12.0 to introduce upcoming NumPy v2 compatibility – it shouldn't be needed for our case because we don't build against the NumPy-C API but just to be sure, I tested the solvers against NumPy v2.0.0rc2 because the IDAKLU-Jax solver uses quite a few NumPy array in its implementation.

pybind11 is scheduled to be a build-time dependency through #3564, earlier through #3560.

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist:

• No style issues: $ pre-commit run (or $ nox -s pre-commit) (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: $ python run-tests.py --all (or $ nox -s tests)
• The documentation builds: $ python run-tests.py --doctest (or $ nox -s doctests)

You can run integration tests, unit tests, and doctests together at once, using $ python run-tests.py --quick (or $ nox -s quick).

Further checks:

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works
