Is your feature request related to a problem? Please describe. We should create a tiny little tool which does the dirty work for you injecting .design into an existing project...

Describe the solution you'd like

1. Run npx contribute in your terminal
2. Run through a small wizard (e.g. is this your handle/project? which design template? (minimal, basic, extended)
3. Create the stuff for the users and add the badge to their readme
