containerd v1.5.x supports CRI v1alpha2, the API that was available at
the time of release for containerd v1.5. containerd v1.6.x has support
for both CRI v1alpha2 and v1; and is being designated a long term
support release.

kubelet master is removing support for CRI v1alpha2, this action has the
effect of forcing kubernetes master(and kubernetes r.next+) users to move
up to containerd v1.6.x where both CRI v1 and v1alpha2 is supported.

Therefore we need to separate out the pull-containerd-node-e2e job for
containerd 1.5 branch, so that patches can still be made to 1.5 branch
till its EOL. Instead of running against kubernetes master, it will run
against k8s release-1.25 branch (the last release which supports CRI v1alpha2)
