Block dbt deploys from within Astro project

[jeremybeard]

Description

This change blocks the astro dbt deploy command from deploying a dbt project that is within an Astro project. This use case is not supported because it can create unexpected behavior when the full Astro project is then deployed with astro deploy.

🧪 Functional Testing

• Unit tests added/updated
• Manually tested within and outside of an Astro project
