fix: set packaging minimum version

Set packaging minimum version to 22.0 to avoid the following error with
setuptools 71.x:

TypeError: canonicalize_version() got an unexpected keyword argument 'strip_trailing_zero'

Likelyhood of encoutering this error increased since commit
e4239bd which bumped minimum version of
setuptools from 65.5.1 to 70.0.0
