> Today we can only update a document by deleting all previously indexed documents for
the given term. In some cases like when deletes are not `final` in the way that documents
that are marked as deleted should not be merged away a `soft-delete` is needed which is possible
when doc-values updates can be done atomically just like delete and add in updateDocument(s)
>     
> This change introduces such a soft update that reuses all code paths from deletes to
update all previously updated documents for a given term instead of marking it as deleted.
This is a spinnoff from LUCENE-8198
