Discord: Breaking Changes notifications

[chris400]

As a user I would like to be notified of any breaking changes.
Currently I would need to take a look at discussions regularly and manually.

It would be great to be notified specifically for any breaking changes as in https://github.com/community-scripts/ProxmoxVE/discussions?discussions_q=label%3A%22breaking+change%22
Github Webhooks should be able to do that:
https://docs.github.com/en/webhooks/webhook-events-and-payloads?actionType=labeled#discussion

You could use a separate channel in Discord or separate role for these notifictions.
