[Feature] Freshness report in dbt docs

### Is this your first time submitting a feature request?

- [x] I have read the [expectations for open source contributors](https://docs.getdbt.com/docs/contributing/oss-expectations)
- [x] I have searched the existing issues, and I could not find an existing issue for this feature
- [x] I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

### Describe the feature

As far as I've been able to understand you can not see the freshness report in the docs that dbt can generate.
This would be a very nice feature, just a simple list that shows basically the content of the sources.json that `dbt sources freshness` generates.
