Instrumentation for pgStatStatements and logicalReplication queries not adding customQueriesConfigMap

### Description
Enabling the pg_stat_statements extension on the chart with `cluster.monitoring.instrumentation.pgStatStatements: true` correctly enables the extension, creates the configmaps with the queries `-monitoring-logical-replication`, `-monitoring-pg-stat-statements` but does not add them to the `customQueriesConfigMap` on the cluster.

### Result
No metrics are emited for pgStatStatements and logicalReplication.
The cluster only has the injected cnpg-default-monitoring.

### Expected Result
When enabling the instrumentation the metrics should be emited by the pod, so they should be mounted.

I can make a PR for this

Start by locating the chart templates handling cluster.monitoring.instrumentation.pgStatStatements and customQueriesConfigMap, then trace how the logical-replication and pg-stat-statements query ConfigMaps are connected to the cluster. Done means enabling the instrumentation mounts both query sets and the pod emits their metrics; the payload names no specific files or tests.
