feat: route generate data CTA to developer chat

[AdityaHegde]

1. Routing generate data CTA to developer chat if the flag is enabled.
2. Updating the home page to show new CTAs that make sense for the new flow.
3. Also updating the home page to who a "generating data" message.

UXQA:

1. When generating data from non-home page, we only need display the prompt modal if the developer_chat feature flag is disabled. If developer_chat feature flag is enabled, we don't show the prompt modal and instead show the ChatBot
2. Generate data action should continue with the current conversation for now
3. I don't see any generating animation. Just a static image:
   some things that I don't see from the Figma is that the designs call for some color on the image as well as the text: "✨ Generating your sample data". Also need some padding between the image and the text below:
   .
   The image as well as the title text should be pulsing!
4. Could we use the display names of the demo projects instead of names?
