Breaking Changes

• Removed unused fields from stg_recurly__subscription_history:
  • converted_at
  • has_started_with_gift
• These fields were removed since they are planned for future deprecation in the Fivetran Connector and are not utilized in the downstream transformation package.

Under the Hood:

• Incorporated the new fivetran_utils.drop_schemas_automation macro into the end of each Buildkite integration test job. (#14)
• Updated the pull request templates. (#14)
