[Feature] ERD in dbt docs

[MazrimT]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

I want to be able to see the ERD in dbt docs.
DBT can create relationships in the database, but does not show it in the docs when its generated.
