CLI: Split `Install dependencies and start project?` into two separate prompts

[AriPerkkio]

Is your feature request related to a problem?

From @sulco:

Install dependencies and start project.

This should not be a single question. These are absolutely different actions and a developer should be able to install the dependencies as a wrap up of installation process in their terminal app but then open the dev server in their vscode. Making these two a single action might get you a tutorial in a browser fastest, but if you're actually intending to work on the code, this is a super confusing dx.

Describe the solution you'd like.

CLI should prompt two separate questions:

• Install dependencies?
• Start the project?
