Would it be possible to add a hook that can be configured by the git backend to notify dokuwiki that it needs to pull immediately?

github, gitlab, vsts all support such hooks, and would make a better alternative than polling.

would be possible, so if anybody is interesting to provide a endpoint to trigger the update, please, send a pull request
