 This allows you to set for example GOOSE_PROVIDER__TYPE to be "databricks" by default if you want (so when people start Goose.app - they will get that out of the box). There is no way to set an api key in that bundling as that would be a terrible idea, so only use providers that can do oauth (like databricks can), otherwise stick to default goose.
