## What this PR does
Aligns the vendored CloudNativePG chart metadata and CRDs with the
already-pinned 1.27.3 operator image. CNPG 1.27.3 stores the
instance-manager session identifier in
`Backup.status.instanceID.sessionID`; the 1.27.1 CRD prunes that field,
causing false instance-manager restart errors and failed backups.
Fixes#3479.
### Screenshots

### Release note
```release-note
fix(postgres-operator): align CloudNativePG CRDs with the pinned 1.27.3 operator image so PostgreSQL backups no longer fail with false instance-manager restart errors
```
