[FR] improve genkit init

[hemanth]

~/labs/genkit-chat 
❯ genkit init 
Error: The runtime could not be detected or is not supported. Supported runtimes: node

genkit init at bare minimum should do an npm init if package.json isn't present.

More better if:

~/labs/genkit-chat 
❯ genkit init 
? App name
 genkit-demo # mkdir and cd
? Select the deployment platform: 
  Firebase 
? Select the deployment platform: Node.js
? Select the model provider: 
❯ Google AI 
? Select the model provider: Google AI
