Reduce Agroal pool logging

In Quarkus LangChain4j, we ended up with log entries like:
2024-09-04 15:59:04,507 INFO  [io.agr.pool] (executor-thread-1) Datasource '<default>': Pool interceptors: [io.quarkiverse.langchain4j.pgvector.PgVectorAgroalPoolInterceptor_X57UyAR6Zcr9HEqaFpEAQVtGhO8_Synthetic_ClientProxy@762e5bc7 (priority 0)]

It's not something the user should be bothered with.
