Remove hardcoded beta binding between Moonraker and Klipper.
This could result in a user getting stuck on a commit that requires
a future patch.
The original purpose of binding versions was to avoid a scenario
where Klipper introduces a feature incompatible with the current
Moonraker beta. Rather than binding the better solution is to
fix the incompatibility and tag a new beta.
