Add new oracle-ee-cdb engine to the valid db engine on rds validator

[rdenadai]

This is a new PR addressing comments from #2334 and should "fix" Issue #2333

Sorry for closing the old one and open a new ... but I wasn't able to fully do all operations on my work account, so I moved to my personal one.

Pull Request Overview

Adds support for the oracle-ee-cdb engine and modernizes the RDS engine validation by converting the valid engines list to a set and adding several new engine types. This update addresses issue #2333 by including the missing oracle-ee-cdb engine type.
