Use FOLIO fork of vertx-sql-client and vertx-pg-client

The FOLIO fork https://github.com/folio-org/vertx-sql-client of the upstream vertx-sql-client and vertx-pg-client driver contains these patches:

• RMB-739 "patch idle connection release in the forked vertx-sql-client driver" This will make RMB's DB_CONNECTIONRELEASEDELAY work again. RMB's DB_CONNECTIONRELEASEDELAY is 60 seconds and releases unused database connections when they have been returned to the pool and haven't been reused for 60 seconds, see https://github.com/folio-org/raml-module-builder#environment-variables
• FOLIO-2840 "Unsigned long HexSequence for name of PgPreparedStatement" This fixes duplicate names causing "prepared statement "XYZ" already exists".

Change RMB dependencies to use the forked version instead of the upstream version.
