Merge pull request 'fix(longhorn): retire the failed 2TB PERC disk on talos-cp-2' (#62) from fix/retire-longhorn-disk4 into main

The StatefulSet database could not attach its Longhorn volume, so the branch
runs the database as a CNPG Cluster instead. This pins the Application to that
branch for the test; it returns to the default branch once the branch merges.
