Address additional lint issues

- the prealloc warning in internal/bridge/crunchybridgecluster/watches.go
doesn't occur in 5.8+ so it wasn't handled previously
- the gosec conversion issue in internal/controller/postgrescluster/instance.go
is handled similarly in 5.8. This slice should always be small.
