dbt schema is not compatible with dbt docs

When I run `dbt docs generate` with a source that has for example:

```
tables:
- name: account_in_chart_of_accounts
description: "{{ doc('atlas_account_in_chart_of_accounts_table') }}"
columns:
- name: chart_of_accounts
data_type: string
description: "{{ doc('sap_atlas_chart_of_accounts') }}"
```

The Generated docs do not show the type.

When I change the **data_type** to **type: string** then it works but the schema validation on vscode fails.
