k3s: clarify uprev version (1.22.6) and PV
k3s: clarify uprev version (1.22.6) and PV

The shortlog of the previous uprev incorrectly stated that
1.23.x was the target. There are issues remaining with that
version, so the uprev was contained to 1.22.x

We also typically do NOT use the exact release tag, since
fixes are continually arriving post release, and with the
extensive go mod vendor process, it doesn't accurately
represent the version.

As such, we switch to: v1.22.6+k3s1+git${SRCREV_k3s}, for
finer grained version tracking.
