address review: remove tox envs and pre-commit hook

Per review feedback from @emdneto:
- Remove changelog/new-changelog tox envs (they generate CI jobs)
- Remove pre-commit hook (not all PRs need changelog, PR number
  unknown at commit time)
- Simplify CONTRIBUTING.md to document direct file creation
- Regenerate misc.yml
