[db/oracledb] Promote Oracle DB connection attributes to RC

[sudarshan12s]

Fixes #3753

Changes

This PR promotes the Oracle DB connection attributes referenced by span.db.oracledb.client from development to release_candidate.

db.oracledb.client is already marked as RC, but it referenced these lower-stability attributes:

oracle.db.domain
oracle.db.instance.name
oracle.db.name
oracle.db.pdb
oracle.db.service

Per the change introduced in #3752, a group should not reference attributes with lower stability than the group itself unless those attributes are opt_in. These Oracle DB attributes are referenced as Recommended, so they need to be promoted to RC.
