Allow using variables in Webhook URL

[JakobDev]

What's the problem this feature will solve?

I'm currently using Read the Docs together with Codeberg which uses Forgejo (a fork of Gitea). I know, that there is no full support of Gitea, so I'm using the Generic things. using the incoming GitHub Webhook works for triggering builds, as described in the Documentation. But I also want to report the status of the Build to Codeberg. I'm trying to use the build status webhooks to call the Forgejo API. But thres ne big problem: The API endpoint want the commit in the Path, was is currently not possible.

Describe the solution you'd like

Allow using variables in the Webhook URl, so I can use something like https://codeberg.org/api/v1/repos/Owner/Repo/statuses/{{ build.commit }} as the URL.

Alternative solutions

I don't have a Idea for a Workaround.
