Steps to Reproduce

2. Run a test using this mock

No response

References

This issue is referenced in a Terraform issue related to mocking blocks from datasources: hashicorp/terraform#37862 (comment)

It is stated there that using blocks as datasources instead of attributes are considered incorrect and are to be replaced by structural attributes instead.

I assume this bug could be fixed here by using a similar syntax to the datadog_users datasource here
