Add Oracle

[blafond]

Fix #1532

I disabled UTCTest for Oracle due to 4 test failures.

• testDate()
• testCalendar()
• testLocalDateTime()
• testZonedDateTime()

Example:

 throws jakarta.persistence.NoResultException: No result found for query [from ThingInUTC where date=:dt]
	//	     at app//org.hibernate.reactive.query.spi.ReactiveAbstractSelectionQuery.reactiveSingleResult(ReactiveAbstractSelectionQuery.java:175)
	```
