Playwright - Fix delete cookies check & update test_synonyms file

[emilghittasv]

• There are some cases in which deleting the playwright user session redirects to the login page (depending on which page the session cookies deletion was performed). Since the login page doesn't contain the top navbar options, we must treat the login page as a pass while checking that the user was indeed signed out after the session deletion. This fix should improve the execution time on those particular tests by breaking out from the attempts/retry loop.
• It seems that searching for "popups" will also return results containing "pops up". I'm adding that to the synonm list.
