Support meta attributes in documentation editor

[alangner]

Describe the feature

dbt allows to add metadata to the model yaml files on the table and column level: https://docs.getdbt.com/reference/resource-configs/meta

It would be nice if the documentation editor supports to set/write these attributes as well.

Describe alternatives you've considered

Editing yaml files manually

Who will benefit?

Everybody who enriched the dbt models with custom metadata
