Review Comment:
   This Solr-scheme example is obsoleted and no longer needed in Lucene 
Javadoc, can you please remove the XML stuff? Instead, you can list the 
parameters like 
[this](https://github.com/apache/lucene/blob/main/lucene/analysis/common/src/java/org/apache/lucene/analysis/shingle/FixedShingleFilterFactory.java).
   Also, I suppose `@since` should be `9.2.0` (the next minor release).
