Update pipeline to generate caids: add gnomAD v4 and update Hail usage

[nadeaujoshua]

This PR includes 2 updates to the data pipeline that generates a Hail table for caids:

1. Add gnomAD v4 to the pipeline
2. Update Hail imports and their usage to be compatible with newer versions of Hail
   • The get_caids module uses a number of Hail utils that have either been changed, removed or replaced since its last update
