Use hub test cases for test result issues
Part 4 of https://gitlab.com/gitlab-org/gitlab-qa/-/issues/639
Updates the reporting script to parse the issue results link out of the linked Test Case's description and to automatically add a link in the description(Test Cases don't have the linked issues widget) of the Test Case to the reporting issue it finds/creates if not linked already.
Should not be merged until https://gitlab.com/gitlab-org/gitlab/-/merge_requests/68677 has reached production.
