Description

As outlined in parent issue...

• use ClassicSimilarity as per-field default when luceneMatchVersion < 6.0
• use BM25Similarity as per-field default when luceneMatchVersion >= 6.0

SOLR-8329 can be used for folks who really want ClassicSimilarity as the per-field default but also really want luceneMatchVersion >= 6.0 for any other reasons
