kubectl get volumesnapshotlocation falls back to NAME and AGE, while
BackupStorageLocation beside it shows provider and phase. This follows
the same pattern for the remaining location type.
Phase is worth surfacing here because the CLI does not print it.
velero snapshot-location get shows only NAME and PROVIDER, so
status.phase, which carries the same Available/Unavailable enum as
BackupStorageLocation, is currently not visible from either tool.
Raised as an open question on #10199 and left out of #10200 to keep that
change to the two types the issue was filed about.
