[pyup-bot]

This PR updates pytest-asyncio from 0.21.1 to 0.22.0.

Changelog

0.22.0

* Class-scoped and module-scoped event loops can be requested
via the _asyncio_event_loop_ mark. [620](https://github.com/pytest-dev/pytest-asyncio/pull/620)
* Deprecate redefinition of the _event_loop_ fixture. [587](https://github.com/pytest-dev/pytest-asyncio/issues/531)
Users requiring a class-scoped or module-scoped asyncio event loop for their tests
should mark the corresponding class or module with _asyncio_event_loop_.
* Test items based on asynchronous generators always exit with _xfail_ status and emit a warning during the collection phase. This behavior is consistent with synchronous yield tests. [642](https://github.com/pytest-dev/pytest-asyncio/issues/642)
* Remove support for Python 3.7
* Declare support for Python 3.12
