AudioParamDescriptor - replace page macro with code fragment

[hamishwillee]

This is part of fixing #3196

The AudioParamDescriptor example was pulled from AudioWorkletNode/parameters using page macro. This cuts out just the relevant part of the example that shows this code being used and links to the larger example.

Further, the AudioWorkletProcessor.parameterDescriptors() static getter was pulling the values of AudioParamDescriptor using the page macro. Here I decided to just copy in the values. I could have just linked but really it seems like duplicating is worthwhile for understanding easily how to use the getter.
