Docs: Add full examples to readthedocs

[brendanreardon]

Feature description

At the moment, only snippets from examples are included under Constraints or Recipes. There should be an option to view full examples within the readthedocs.

Some potential options:

1. Link out to the example .yaml and .json files on GitHub.
2. Add orphan pages on readthedocs for each .json and .yaml example. These can be hyperlinked next to each example's drop down when used in the docs.
3. Add a section called "Examples" that includes headers for each example. There, we can include .yaml and .json full examples and migrate the documentation for Examples to the readthedocs
