py-test-xprocess: updated to 0.22.2

0.22.2 (2023-01-05)
-------------------
- Python 3.10 is now officially supported
- `surrogateescape` will now be used as error handling strategy for encode/decode operations.
- Make log files persistency, added in `0.21.0`, optional, defaulting to True. The previous logging behavior (prior to `0.21.0`) can be enabled by setting `persist_logs` flag to `False` when calling `XProcess.ensure`.
- Fix resource warnings due to leaked internal file handles
- Ignore zombie processes which are erroneously considered alive with python 3.11
