Fix coverage report [RUN ALL RSPEC]
What does this MR do?
- Allow to run all the RSpec jobs with 'RUN ALL RSPEC' in MR title
- Limit the folders that are included in the coverage report. The goal is to make the coverage report more accurate.
Correct coverage report can be seen at https://gitlab-org.gitlab.io/-/gitlab/-/jobs/630816674/artifacts/coverage/index.html (currently 97.56%).
Closes gitlab-org/quality/team-tasks#557.
