Review comment:
I guess, I assumed that we may access Lucene90HnswVectorsReader
constructor also when we don't need to do any graph data and graph search, but
just to check an index as in `CheckIndex:checkIndex`. But may be this is a
wrong assumption outside tests, and we always access segment readers when need
to search them.
