Add dbt-project type mapping

This change introduces a new `dbt-project` repository type mapping, desgined specifically for dbt (data build tool) projects.
All dbt projects require a standard `dbt_project.yml` configuration file at a minimum, which is used in this script.
For reference, see https://docs.getdbt.com/docs/build/projects
