Lets a parent issue in this repo close itself once all its sub-issues are closed, using the shared workflow in Redux_Build_System. It's a second job in rbs.yml, so no workflow file is added.

Features

• rbs.yml gains a close-parents job that calls ReduxISU/Redux_Build_System/.github/workflows/close-finished-parents.yml@main. It closes this repo's open issues labeled close-when-subissues-done once all their sub-issues are closed. Unlabeled issues, trackers included, are never touched.
• New triggers: an issue closing, hourly (for sub-issues in other repos), and on demand. These run only close-parents. build-test still runs only on pushes and PRs.
• The concurrency group adds the event name, so an hourly run can't cancel a push run on the same branch.

Same change as ReduxISU/Redux#950. Merge ReduxISU/Redux_Build_System#10 first: this calls its @main.

The rbs check fails at startup ("workflow file issue") until ReduxISU/Redux_Build_System#10 merges. GitHub checks every workflow rbs.yml calls before starting a run, and close-finished-parents.yml isn't on rbs main yet. I confirmed the file is valid by pointing it at the rbs PR branch for one run on #50: build-test ran and close-parents was skipped, as intended. Then I reverted that. After #10 merges, re-run the rbs check here.

Marked as draft until ReduxISU/Redux_Build_System#10 merges. Merging this first would make every rbs run in this repo fail at startup, because the shared workflow it calls wouldn't exist yet. Once #10 is in, I'll mark this ready and re-run the check.

Closing this: we decided to close parent issues by hand, since each one gets checked before it closes anyway. Removing the automatic job everywhere instead (Redux_Frontend and Redux_Build_System get small removal PRs).
