Make lucene snapshot repository exclusive to lucene packages (#53353)

When depending on lucene snapshots we point maven at our own s3 backed
repository. However, in this case lucene packages should only be
retrieved from this location, and no other packages should ever be found
in that repo. This commit makes the maven repository exclusive to lucene
packages.
