Add query builder

[sabineschaller]

On readme, we had the "try it out" functionality. While we don't need the button to actually try out a request, we want the query builder that builds up the query in multiple programming languages.

We'll need to discuss how to handle this issue. At the time this was created, Starlight couldn't support this functionality. It's part of the reason we manually added the TS code snippet pieces. Maybe there's a better way to handle this now.
