Fix execution for Python 3.11

Fixes execution on Python 3.11

Prevents the following error:

I just did as I was told by Python

trailing spaces

The version string test fails, unfortunately... It is a rather artificial test to ensure basic functioning. Could you please look at it to make the pipeline green

The test for version 1.0 should be removed. It just say that my forks is missing tags from the main repo. I assume that all future forks will fork after the release/1.0.0 and that Gitlab forks will inherit tags at the moment of fork like Github. Otherwise, the test failure is suprising.

• bbcefe16 - fix: MappingProxyType is not a constant and should therefor use default_factory
