Update HNSW indexes to Lucene 10

[lintool]

Note here that I'd like to merge into the lucene10 branch, not master.

This patch updates hnsw and hnsw-sqv x onnx and cached for both BEIR and MS MARCO: code updated, parameters re-tuned.

@zdann15 can you please take a look also?

BTW, int8 was renamed to sqv because ScalarQuantizedVectors is the name of the Lucene class that implements the quantization.

Specifically: https://lucene.apache.org/core/10_3_2/core/org/apache/lucene/codecs/lucene99/Lucene99HnswScalarQuantizedVectorsFormat.html

And according to the doc: "Constructs a format using default graph construction parameters with 7 bit quantization", so int8 is actually a misnomer.
