Use FilenameProvider in ray dataset instead of BlockWritePathProvider

[raghumdani]

We currently use BlockWritePathProvider which is deprecated as of 2.20.0. Hence, the Ray datasets will only work with deltacat in Ray versions < 2.20.0. Currently, ray data code path isn't being used in compaction and hence it does not impact compaction. We have made it compatible with new BlockWritePathProvider implementing call method. Hence, this issue tracks migrating off of BlockWritePathProvider to FilenameProvider for ray data based reads.
