Remove Dask upper version limit

[thehomebrewnerd]

• Remove Dask upper version restriction
• Closes Support dask 2022.8.0 #1498

Removes the upper bound on dask[dataframe] and updates test_to_disk_with_latlong to ignore the index column since we can't rely on Dask maintaining the index column during serialization and the latlong_df fixture does not utilize an index column, so the underlying dataframe range/int index isn't meaningful in the test.
