Merge ~fossfreedom/ubuntu/+source/ubiquity:hidefrombudgie into ubuntu/+source/ubiquity:ubuntu/devel

[fossfreedom]

Ubuntu Budgie for mantic have removed ubuntu indicators from its seeds. As such the ubiquity panel is now blank.

This PR hides the blank panel. We don't need a panel for our legacy ISO.

[Benjamin Drung (bdrung)]

Merged into https://code.launchpad.net/~ubuntu-installer/ubiquity/+git/ubiquity/+ref/main and it will be part of the next ubiquity upload.
