feat(RELEASE-2092): get snapshot from kubearchive if deleted

The catalog tasks mostly use the get-resource script in
release-utils-repo to get Kubernetes resources. For snapshots, this
script has been modified to fallback to kubearchive if the resource
had been deleted [1].

This approach doesn't work if the get-resource script isn't used to
get the snapshot. This commit modifies the one instance where this
happens to use the get-resource script, ensuring that the kubearchive
fallback is used.
