docs: add/reformat return types for cloud RAD docs - #1582

• In order for the Return table to show up in the docs, the type of the return object must be in the Returns docstring
• I also removed two examples from docstrings - they don't format properly in our docs and I felt they were encompassed in other samples. If we want to keep them we can, I'll just need to reach out to the Cloud RAD team to understand how they need to be formatted

Fixes #1438 once the Cloud RAD job runs after this is merged 😄
