[SPARK-32876][SQL] Change default fallback versions to 3.0.1 and 2.4.…

…7 in HiveExternalCatalogVersionsSuite

### What changes were proposed in this pull request?

The Jenkins job fails to get the versions. This was fixed by adding temporary fallbacks at apache#28536.
This still doesn't work without the temporary fallbacks. See apache#29694

This PR adds new fallbacks since 2.3 is EOL and Spark 3.0.1 and 2.4.7 are released.

### Why are the changes needed?

To test correctly in Jenkins.

### Does this PR introduce _any_ user-facing change?

No, dev-only

### How was this patch tested?

Jenkins and GitHub Actions builds should test.

Closes apache#29748 from HyukjinKwon/SPARK-32876.
