📚 Description

Wanted to help with stubbing out and adding --dotenv to dev, preview and build but for build I would think this would be an override during build but I could not find and overrides so I left build out for now until I can learn the best way to override it.

• nuxi dev
  • [Added][--dotenv] option - relative to rootDir defaults to rootDir
• nuxi preview
  • [Added][--dotenv] option - relative to rootDir defaults to rootDir
• nuxi build
  • [Added][--dotenv] option - relative to rootDir defaults to rootDir

I will update docs once I have more information!

Thanks 💚

Nice work! For build command you can pass dotenv option to the loadNuxt.
