feat: [+] pr comment with test summary per spark version

[eruizalo]

Description

This change is trying to get the testing more visible and accessible. Thanks to this we could see the incrementing number of tests across different versions and detect if a test should be somewhere else. This may not be the best solution, but it is a starting point.
