python3Packages.trio: 0.22.0 -> 0.22.2

https://github.com/python-trio/trio/releases/tag/v0.22.1
https://github.com/python-trio/trio/releases/tag/v0.22.2

The package now requires pytest-trio for its tests to succeed, which
resulted in an infinite recursion. Crimes have therefore been committed
to resolve this unfortunate situation.
