Get auto-generate notes working

[pydanny]

This is the GH API function I can't get to work even on public repos: https://docs.github.com/en/free-pro-team@latest/rest/releases/releases?apiVersion=2022-11-28#generate-release-notes-content-for-a-release

Here's sample GH CLI code hitting a public repo that isn't working:

gh api \
 --method POST \
 -H "Accept: application/vnd.github+json" \
 -H "X-GitHub-Api-Version: 2022-11-28" \
 /repos/pydanny/listo/releases/generate-notes \
 -f tag_name='0.6.0' --verbose
