cmd/vet: don't report "loop variable captured" error for versions >= go1.22

[griesemer]

The new loop variable semantics (#60078) is enabled for go1.22 so go vet shouldn't report an error for captured loop variables anymore.

The playground at tip shows the new loop variable semantics but still reports a vet error.

Related to #57063.

Tentatively marking this as a release blocker.

Indeed! (I'm 6h behind despite being in the same time zone... :-)
Thanks for opening that other issue.
