Add docs/example for (de)serialization of framework types, especially collections

[azrdev]

Module version

v1.10.0 currently referenced by the docs

Use-cases

I'm implementing an attribute with a complex type (list of nested objects). The docs [1][2] show how to define the schema, but only have cursory examples for converting to/from framework types to my own (backend) type hierarchy. I found some forum discussion and other provider code (see below) to implement the conversion myself, but an example in the framework docs itself really is missing in my opinion.
