Bump propcache to 0.2.1

[bdraco]

Proposed change

changelog: aio-libs/propcache@v0.2.0...v0.2.1

There is a fix to ensure wheels get built with a compatible Cython version which would only affect core installs that are building their own wheel locally

We were missing wheels for armv6l w/Python 3.13 https://wheels.home-assistant.io/musllinux/ because skip-binary was not set on the core wheels build for propcache
