Bump pyo3 from 0.23.5 to 0.24.2 (#18460)

Also bump pythonize from 0.23.0 to 0.24.0, otherwise we couldn't compile
as pythonize 0.23.0 required pyo3 "^0.23.0".

Addresses
[RUSTSEC-2025-0020](https://rustsec.org/advisories/RUSTSEC-2025-0020),
although Synapse is not affected as we don't make use of
`PyString::from_object`.

[pyo3 0.24.x](https://github.com/PyO3/pyo3/releases/tag/v0.24.0) include
some performance optimisations apparently, and no breaking changes.
