Shape a delightful Blueprints API that's useful and easy to use for WordPress developers

Let's ship a stable version of the Blueprints API that allows customizing Playground instances with specific plugins, themes, content and more.

Specifically, let's:

• Engage with WordPress plugin authors for user testing, much like we'd do with a website. Let's ask them to prepare a Blueprint for their plugin and take note of any friction points, feedback, and bugs
• Reach out to the wider community and encourage feedback via GitHub issues
• Polish the documentation for a delightful onboarding experience
• Fix any remaining bugs

We'll know this issue is solved when:

• 10 people successfully set up a Blueprint without getting stuck
• There are no known major bugs

Currently, Blueprints expect step-by-step instructions. Could there be a simpler, declarative API? For example:

{ "plugins": ["gutenberg", "woocommerce"], "theme": "twentytwentyfour", "posts": [ {"title": "My first post"} ] }

Review the linked Blueprints API documentation and current step-by-step Blueprint format first. Validate proposed API and documentation changes with plugin authors and the wider community; done means 10 people set up a Blueprint without getting stuck and no known major bugs.
