dev: update bug_report issue template

- Moves (and shortens) checklist to bottom so they don't hog content
  previews in Discord notifications (or notifications elsewhere).
- Consolidate guidelines into a shorter list rather than checkboxes,
  because I've caught folks blindly checking them off too often.
- Adds AI disclosure checkboxes.
- Emphasize backtraces (because few posters remember to include them).
- Revise to be a little more concise (hoping that less to skim will make
  folks more likely to read it, or at least grok it faster).
