[release-1.30] Bump CSI snapshot controller chart for CRD updates

[brandond]

Proposed Changes

Update volume snapshot CRDs from upstream:
https://github.com/kubernetes-csi/external-snapshotter/tree/v8.1.0/client/config/crd

Major change is that most validation has been moved to CEL expressions instead of using the webhook.

Ref: rancher/rke2-charts#542

Types of Changes

CRD bump

Verification

Apply VolumeSnapshot with empty spec.volumeSnapshotClassName and receive error from validation rules:

The VolumeSnapshot "new-snapshot-demo" is invalid: spec.volumeSnapshotClassName: Invalid value: "string": volumeSnapshotClassName must not be the empty string when set
