ci: Use continuous branch for now

We are hitting issues with a-h-t on CAHC right now failing due to an
`atomic scan` issue and preventing promotion of continuous content to
the smoketested branch. This is then blocking our CI which needs a newer
tree with the latest glib2 baked in. Let's unblock our CI for now by
rebasing on the continuous branch. We'll drop that hack once the a-h-t
issues are ironed out.

Closes: #1365
