gha: docs build `Compile JavaDoc` step error message

[jbampton]

For the docs build workflow when we compile the Java docs there is a red error message seen at the next link under heading Compile JavaDoc right at the end of the messages

https://github.com/apache/sedona/actions/runs/14141493590/job/39623420701?pr=1889

It shows as:

Error: Error fetching link: /home/runner/work/sedona/sedona/common/target/target/apidocs/package-list. Ignored it.

I am not sure about this issue. Could be a path issue or missing file etc. You can read up on the javadoc tool here:

https://docs.oracle.com/javase/8/docs/technotes/tools/windows/javadoc.html

And this is a very long page and if you search for the term package-list it appears in many places.

The next link has the example package-list file:

https://docs.oracle.com/javase/8/docs/api/package-list

And the relevant line in our workflow:

https://github.com/apache/sedona/blob/141a36829f888ba28f004faafd5c34c6f2895fae/.github/workflows/docs.yml#L45

Opened PR #2157 to fix the JavaDoc package-list error by updating the workflow copy path. Also restored missing Spotless and Scalastyle config files for successful builds. Please review!
