Playground defaults should be take from example

[MichaelErmer]

What problem will this feature address?

Playground and examples are currently unlinked.

Describe the solution you'd like

The playground should use the values from the example as default data, the authorization and path parameters from playground should be mirrored to the example, so that usable CURL / Js.. code can be copied from the docs.

Describe alternatives you've considered

none

that will need to add the example code generator to client bundle, but I think it should be fine
