workflow adjustments

[sfc-gh-jcieslak]

1. What GitHub issue is this PR addressing? Make sure that there is an accompanying issue to your PR.

   N/A

2. Fill out the following pre-review checklist:

   • I am adding a new automated test(s) to verify correctness of my new code
   • I am adding new logging messages
   • I am adding new credentials
   • I am adding a new dependency (file filtering in GHA)

3. Please describe how your code solves the related issue.

Adjust workflows:

• Remove unused workflows (please see create_req_files.yml; wasn't sure if it's used or not)
• Adjust testing workflow
  • Remove push event as we're mostly concerned about tests on PRs rather than on pushed changes
  • Change workflow_dispatch parameters (previous ones were not used)
  • Add a new job that runs first and:
    • Extracts PR data and verifies if the pipeline was run with the correct SHA (should be equal to head)
    • Checks for files changed to determine if tests should be run or not
  • Adjust ifs for each job, so that it skips the work when it should
  • Adjust checkout action in each job, so that the correct code is chosen

Also, potentially whole jira workflows could be simplified to just one workflow that creates tickets.

How about moving to latest version ?
