E2E tests: remove resources after tests

What does this MR do and why?

Sometimes tests fail in live environments due to a build-up of test data which can break Ui components or cause api calls to timeout. This MR cleans up some groups and projects that have been building up against the qa-user1 test user.

These particular groups were discovered while investigating #372258 (comment 1340024017)

How to set up and validate locally

Running each individual test, although it is probably more useful to view pipeline results.
