[FIX] doc: branch name in configuration

The branch name is used in the version switcher, so the master branch should have a version of "master".

Maybe the release could be the revision hash? Not sure how to extract it from the repo.
[IMP] event: auto confirmation option, to automatically
confirm events. In a simple flow, having to manually confirm registrations and events
can be tedious, leading to the addition of this option.
