Removed vocab study

[dogversioning]

This moves the contents of the vocab study out of the main studies folder (#286 ), and moves a subset of it's configuration to test_data so that we still have coverage for building tables from static parquet files.

Checklist

• [X] Consider if documentation in docs/ needs to be updated
  • If you've changed the structure of a table, you may need to run generate-md
  • If you've added/removed core study fields that not in US Core, update our list of those in core-study-details.md
• [X] Consider if tests should be added
• [X] Update template repo if there are changes to study configuration in manifest.toml
