Package source is not compatible with python 3.10 in ubuntu 22.04

[Reza]

Starting plover and clicking on Output -> Enable produces this error:

ERROR: engine update failed.
AttributeError: module 'collections' has no attribute 'Sequence'

The error seems to be coming from:

/usr/lib/python3/dist-packages/plover/system/__init__.py:

assert isinstance(keys, collections.Sequence)

This has been fixed in plover's source code (by switching to collections.abc), however it looks like the ubuntu package source is older.
