Config checker doesn't recognize `akka.persistence.r2dbc.connection-factory.connection-factory-[x]-[y]` properties.

For example:

WARN  akka.diagnostics.ConfigChecker - Configuration recommendation: akka.persistence.r2dbc.connection-factory-1-1.dialect is not an Akka configuration setting. Did you mean one of 'akka.persistence.r2dbc.postgres.dialect', 'akka.persistence.r2dbc.yugabyte.dialect', 'akka.persistence.r2dbc.h2.dialect'? Is it a typo or is it placed in the wrong section? Application specific properties should be placed outside the "akka" config tree. Related config properties: [akka.persistence.r2dbc.connection-factory-1-1.dialect]. You may disable this check by adding [typo] to configuration string list akka.diagnostics.checker.disabled-checks.

We get one WARNing for each and every connection-factory-0-0 or connection-factory-1-1 and so on.
