Update pyo3 requirement from 0.18 to 0.21

[dependabot]

Updates the requirements on pyo3 to permit the latest version.

Release notes

Sourced from pyo3's releases.

PyO3 0.18.3

This release fixes an issue with PyDateTime::type_object() incorrectly returning the type object for PyDate, which would cause some is_instance checks to behave incorrectly.

In addition, this release contains a handful of minor quality-of-life corrections over PyO3 0.18.2.

Thank you to the following users for the improvements:

@rmalmain I guess this lacks the same changes on the qemu bridge side

@domenukk I tried to update this dependency in the past, but this update is not possible because of this dependency. If we want the update to work, we need this crate to be up to date as well. Should I open a PR there?

[domenukk]

This needs changes in nautilus - cc @eqv

@rmalmain we got rid of the dependency / included it in the repo now, can you see if we can update pyo3 now?

[rmalmain]

It should be good to go now

Closed in favor of #2459

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
