Now that https://github.com/snapcore/snapcraft/pull/3596 has been
released in snapcraft 6.0.1, drop the prompt that tells users to
disconnect the old framework snap.
Also drop --enable-experimental-extensions from CI because kde-neon
has been declared stable for core20.
Open & save dialogs might fail if it is not running.
org.freedesktop.portal.Desktop is DBus activated and this doesn't play
nicely with AppArmor at the moment.
This prevents the config and the user collection from being
backed up by snapd on update. If the user reverts qelectrotech,
the current collection will thus not be overwritten by the
possibly outdated backup.
Add a migration script that automatically transfers the user's .qet
directory to the new location.
Snapcraft can find its build recipes in 2 places:
* a snap/ directory at the top of the sources;
* a build-aux/snap/ directory, since Snapcraft 3.3;
This commit moves from the former to the latter, so that we can group
all the packaging recipes together.
