[SPARK-28704][SQL][TEST] Add back Skiped HiveExternalCatalogVersionsS…

…uite in HiveSparkSubmitSuite at JDK9+

### What changes were proposed in this pull request?
We skip test HiveExternalCatalogVersionsSuite when testing with JAVA_9 or later because our previous version does not support JAVA_9 or later. We now add it back since we have a version supports JAVA_9 or later.

### Why are the changes needed?

To recover test coverage.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Check CI logs.

Closes #30451 from AngersZhuuuu/SPARK-28704.
