Remove the script which used to be used to create Core release tasks on Jira.
The script is not used any more + is at least partly out of date.
Less cruft in the repository.
Have you added/modified unit tests to test the changes?
No, the script in question has not been covered by the test suite.
If so, do the tests pass/fail?
Have you run the entire test suite and no regression was detected?
Yes, no regression detected.
