UPSTREAM: <carry>: Update group snapshot test rules

Remove rule to skip group snapshot tests. They are already properly
annotated.

We want `[Driver: csi-hostpath].*volumegroupsnapshottable` to be skipped and it
already has '[Disabled:SpecialConfig]'.

We want `[Driver: csi-hostpath-groupsnapshot].*volumegroupsnapshottable to
run in TP jobs and it alrady has `[OCPFeatureGate:VolumeGroupSnapshot]...[Suite:openshift/conformance/parallel]`
