fix: Add Finngen mappings version as a parameter to the disease LUT script

[ireneisdoomed]

Finngen data is updated every so often to include new traits of study which we have to track.
The Finngen studies in the disease LUT was out of sync with the study table (version 5 instead of 6).

This caused a downstream problem in the ETL, when both dependencies are joined to form the study index. All Finngen studies were lacking their respective EFO.

The new table is uploaded here gs://genetics-portal-dev-staging/v2d/220816/trait_efo.parquet

Same schema as the previous one, an increase of 149 new Finngen traits (total of 3011).

There are stydues with a null reported trait, but that doesn't affect any of the downstream pipelines, since this field is not used.

In [4]: lut.count()
Out[4]: 56466

In [5]: lut.filter(F.col('trait_reported').isNull()).count()
Out[5]: 2352
