Lowlatency Kernel is behind in Ubuntu Studio

[Dimitri John Ledkov]

Ideally all flavours would be at 6.2 already, but due to various
reasons they are not.

This is not unique to lowlatency flavour, and applies to kvm, azure,
raspi, and many more kernel flavours all of which are still on v5.19
in Lunar.

We pushed 6.1 out, and migrated, on generic only, to migrate lots of
packages in proposed, specifically nvidia & everything entangled with
it, and thus unblock autopkgtesting of all the userspace packages
which were otherwise failing on v5.19. There is no intention to port
all flavours to 6.1.

in Lunar, no further 6.1 builds will be done for any kernel flavour
for the time being. And v6.2 landing, across all flavours, is in
progress.
