chore(data-warehouse): Moved reset_pipeline from source inputs to schema sync config

[Gilbert09]

Problem

• Currently, the "reset_pipeline" setting (which is used to delete the deltalake table in S3 before syncing, forcing a fresh start) is set on the ExternalDataSource and not the schema, meaning the first schema to run and complete will be reset (e.g. there's a race condition)
• This is needed to reset a handful of tables currently in a bad state from this

Changes

• Moves this onto the schema object directly instead
