Automatically sync assets on release (#4163)

### What

The release assets are now synced automatically on the `release` event
with type `released`


https://docs.github.com/en/webhooks/webhook-events-and-payloads?actionType=released#release

> A release was published, or a pre-release was changed to a release.

Fixes #4133 (no longer needed)
