deps: update pyo3 requirement from 0.18.3 to 0.22.3

[dependabot]

Updates the requirements on pyo3 to permit the latest version.

Release notes

Sourced from pyo3's releases.

PyO3 0.22.3

This release contains a number of quality improvements building upon PyO3 0.22.2.

Python function calls (using .call0(), .call1(args) and .call(args, kwargs)) will now make use of the "vectorcall" calling conventions where possible, which can reduce overheads in many cases.

There have been several fix-ups to PyO3's FFI definitions. A new pyo3::ffi::compat namespace has been added which offers some backwards-compatible implementations of Python APIs otherwise normally only available on recent Pythons.

There have been numerous other bug-fixes and minor tweaks to improve user experience.

Thank you to the following contributors for the improvements:

Looks like pyo3 is up-to-date now, so this is no longer needed.
