Add "join/leave beta" buttons on webUI

Can you add a link in the same place where "update lists" is for updating the installation?
So I won't have to fire up SSH, and type in there... pi, password, pihole -up
Plus you can add "join beta" and "leave beta" there too.

This is already an open request (the pihole -up part). It would help us greatly if you didn't combine multiple requests into one Feature Request. If you want to edit your original post to be the Join Beta/Leave Beta, I will just link to the other Feature Request here for you.

Searching trough the requests is not very easy. Not for features requested almost 1 year ago and not for me at least...

Partially implemented via pihole checkout.
