Unit Tests version doesn't seem to be mapped correctly.

In the documentation from DBT it seems like the correct structure for specifying versions in Unit tests is

```yaml
unit_tests:
- name: my_model_unit_test
model: my_model
versions:
include:
- 2
```

But The https://raw.githubusercontent.com/dbt-labs/dbt-jsonschema/main/schemas/latest/dbt_yml_files-latest.json doesn't seem to be valid for the `versions` attribute.

It's always returning like it's not supported.

Same goes for `config` or `config -> meta` for macros
