Add build detail view beta notification (#11208)

* Add build detail view beta notification

This adds a notification to the corresponding beta build detail view,
and works for both community and commercial. There are two separate
patterns here as the authentication is a little bit different between
the two sites.

* Fix typo

* Update logic to support a link on the new dashboard too
