Add MIGRATE entry about the fact that readVLong() may now read up to 10 bytes. (#13956)
This may be of interest for custom `DataInput`/`IndexInput` implementations
that extend `readVLong()`.

## Migration from Lucene 9.x to Lucene 10.0
+### DataInput#readVLong() may now read negative vlongs
+
+LUCENE-10376 started allowing `DataInput#readVLong()` to read negative vlongs.
+In particular, this feature is used by the `DataInput#readZLong()` method. A
+practical implication is that `DataInput#readVLong()` may now read up to 10
+bytes, while it would never read more than 9 bytes in Lucene 9.x.
