use https://github.com/open-feature/python-sdk-contrib/pull/105/files#diff-c0e0afcf1c3a48af5dba2265c040eb008205f50860791d77316b748205907d2aR87-R144 to verify this. this is the migrated test code from the js flagd provider

see documentation for python semver https://python-semver.readthedocs.io/en/3.0.0-dev.3/usage.html#creating-subclasses-from-version

our code were it fails:

python-sdk-contrib/providers/openfeature-provider-flagd/src/openfeature/contrib/provider/flagd/resolvers/process/custom_ops.py

Lines 131 to 136 in ca76802

	try:
	v1 = semver.Version.parse(str(arg1))
	v2 = semver.Version.parse(str(arg2))
	except ValueError as e:
	logger.exception(e)
	return None

@open-feature/sdk-python-maintainers i think this can be marked as a good first issue
