FluxCD does not apply any Labels to VolumeSnapshotClass resources

[Mobydack]

Describe the bug

FluxCD does not apply the any labels to existing or new VolumeSnapshotClass resources. Even though the labels are defined in the manifest, they are not reflected in the actual VolumeSnapshotClass resource in the cluster after FluxCD synchronization.

Steps to reproduce

1. Create volume snapshot class with labelsCreate or obtain a Kubernetes manifest for an existing VolumeSnapshotClass.
2. Add new labels under metadata.labels in the manifest.
3. Commit the changes to the Git repository managed by FluxCD.
4. Wait for FluxCD to synchronize the changes with the cluster.
5. Check the VolumeSnapshotClass resource in the cluster to verify if the labels have been applied.

Expected behavior

The specified labels in the Kubernetes manifest should be applied to the existing VolumeSnapshotClass resource in the cluster after FluxCD synchronization. The resource should reflect the updated labels as defined in the manifest.
