MINOR: [Java][CI] Fix grep for new nightlies versioning (#14166)

I've noticed that the latest Java nightlies where not uploaded https://nightlies.apache.org/arrow/java/org/apache/arrow/arrow-c-data/. I missed to update the grep on this PR: https://github.com/apache/arrow/pull/14135

I have now tested locally the bash script to validate the repo structure will now be generated correctly:
```
