py-invoke: updated to 1.7.3

1.7.3 2022-09-30
[Support] Fix a non-fatal bug in our setup.py long_description generation \ 
causing 1.7.0-1.7.2 to have malformed description text on PyPI.

1.7.2 2022-09-30
[Bug] Fix errors thrown when comparing Task objects to non-Task objects; such \ 
comparisons are now always false.
[Bug] Refactor CLI parser instantiation such that the tasks.ignore_unknown_help \ 
feature (added in 1.7) works when Invoke is run in --complete mode, i.e. in \ 
tab-completion scripts.
