fix(ci): use app token for releases and consistent CHANGE.md formatting (#571)

- Use GitHub App token for creating releases so JEngine Release Bot
  is shown as the author instead of github-actions
- Remove bold formatting from CHANGE.md entries for consistency
  (all entries now use same format regardless of commit type)
