Available k0s versions for upgrade ?

Before upgrading a cluster to a new version, it can be very handy to have a k0sctl command that lists the available k0s versions we can upgrade to.

Yes I've been thinking about this too. Especially with #923. And it could lead to an automated incremental upgrade using the recommended upgrade path (so something like 1.31.1 => 1.31.8 (latest patch of current minor) => 1.32.8 (latest patch of next minor) => 1.33.4 (latest patch of latest minor) I believe)
