Test-operator has gone through many changes since it was created. The test-operator documentation is the main source of help for users and should be always up to date. This ticket aims to get the current documentation to the best version it can be right now.

DoD:

• Go through the test-operator documentation and mark code or text that is no longer up-to-date, e.g. doesn't work, is misleading
• Propose a PR that fixes all of the found inconsistencies
