Add webhook for deployments

[skttl]

Issue description

Would love a webhook that fires on each deployment. Should include the deployment log.

We are seeing periodic errors, where data extraction is not done after deploying uda changes. It only happens sometimes, mostly it just works. But having a webhook sending the deployment log, we can set up some automation to notify "someone" if a deployment has happened, that copies uda files into the site, but no data extraction has happened.

Can probably be useful for other stuff too.

Hej @skttl! Certainly, your suggestion for a webhook that triggers each deployment, including the deployment log, is a great idea. It will enhance monitoring, aid in troubleshooting intermittent data extraction issues, and enable automation for more efficient response to deployment anomalies. We'll assess the feasibility and consider incorporating this feature into Umbraco Cloud's development roadmap. Thank you for your valuable input!
