pocketbase-bot: write the sync PR against the PR template

The sync PR body had its own Summary and Source headings, so the
autolabeler found none of the template checkboxes it looks for and the
PR came out with nothing but "needs triage". It also never referenced
the issue the command came from.

Write the body the way the template expects, with the Website update
box ticked, which is what a PocketBase sync is. Tested thoroughly stays
unticked and Tested on says not tested, because nothing here was run;
close-invalid-pr-template skips bot authors, so that costs nothing.

Reference the triggering number as Fixes when the command came from an
issue and as a plain mention when it came from a PR comment, where
Fixes would point the PR at itself. issue_comment carries both under
github.event.issue, so the new IS_PR_COMMENT tells them apart.
