ci: comment when publish to npm/pypi finishes successfully (#6628)

This change adds a reusable `post-release-summary` composite action that
automatically figures out the current/previous version, generates diff +
PyPI/npm links, and posts (or updates) the release summary comment
whenever the publish jobs succeed.
