Add screenshots when sso-test fail to help debugging
What does this MR do and why?
Add some screenshots (using selenium) in test-sso job artifacts to help troubleshooting in case of error.
Test coverage
As the error is random, it is difficult to verify the proper functioning of the screenshots in case of an error.
Locally, the screenshots are correctly taken in case of an error, and when there is no error, the pipeline is successful.
