Subject: [PATCH] fix: Inaccurate drop database statement in Oracle (#1807)

* fix: Inaccurate drop database statement in Oracle

Failing test shows that the override for dropDatabase() in OracleDialect is wrong,
so this has been replaced with the correct statement.

Failing test would then require privileges to drop the pluggable database from
the root container level, which are not accessible, so it has been excluded.
