github/ISSUE_TEMPLATE: Update issue form to remove checklist generation.

Update to the issue forms added earlier this year, that seem to generally
be working well.  Improvements in this commit:

- No longer generates TODO checklists in new issues.

- Issue bodies (and therefore email previews) no longer start with the same
  fixed checklist text for each new issue.

This work was funded through GitHub Sponsors.
