Multiple 403 errors in QA tests due to leaking state in tests
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/102477 has introduced a new shared_context which is automatically required by in `/gitlab/qa/spec/spec_helper.rb:5` this may be overriding `imported_project`, `user`, `group` etc and causing other tests to fail. These failures can be identified by a reference to `/qa/specs/features/shared_contexts/github_import_shared_context` in the error stack trace e.g. https://gitlab.com/gitlab-org/gitlab/-/jobs/3254833031#L1874 Should be fixed by revert MR https://gitlab.com/gitlab-org/gitlab/-/merge_requests/102600
