Switch to use LUKS2 by default (or at least optionally)
I noticed that GNOME Disks uses LUKS1 if you choose to encrypt a new partition that is created with it. Given that it was released in 2017 and LUKS2 is the default since Fedora 30 I guess we should also switch to the new, improved and much better™ LUKS2 here, by default.
Alternatively, at least provide an option for that, if you fear the switch for compatibility-reasons.
