build(deps): bump propcache from 0.4.1 to 0.5.2

[dependabot]

Bumps propcache from 0.4.1 to 0.5.2.

Release notes

Sourced from propcache's releases.

0.5.2

0.5.0 and 0.5.1 were tagged earlier today but never reached PyPI: 0.5.0's deploy failed at cibuildwheel's post-build pytest on free-threaded armv7l musllinux (SIGBUS under QEMU emulation while importing the C extension), and 0.5.1's deploy hit a transient sigstore Rekor 502 during the attestation step. 0.5.2 is the first of the three to actually publish.

Features

• Added support for newer type hints and remove Optional and Union from all annotations -- by :user:Vizonex

  Related issues and pull requests on GitHub: #193.

Removals and backward incompatible breaking changes

• Dropped support for Python 3.9 as it has reached end of life.

  Related issues and pull requests on GitHub: #216.

Packaging updates and notes for downstreams

• Changed the Cython build dependency from ~= 3.1.0 to >= 3.2.0, removing the upper version bound to avoid conflicts for downstream packagers -- by :user:jameshilliard and :user:gundalow.

  The upstream Cython version is pinned to 3.2.4 in the CI/CD environment.

  Related issues and pull requests on GitHub: #184, #188, #214.

• Start building and shipping riscv64 wheels -- by :user:justeph.

  Related issues and pull requests on GitHub: #194.

• The :pep:517 build backend now supports a new build-inplace config setting (and PROPCACHE_BUILD_INPLACE environment variable) for controlling whether to build the project in-tree or in a temporary directory. It only affects wheels and is set up to build in a temporary directory by default. It does not affect editable wheel builds; they will keep being built in-tree regardless.

  Here's an example of using this setting:
