Refactor C# API References

[Whipstickgostop]

Is your feature request related to a problem? Please describe. Currently the C# pages are a mixture of autogenerated method definitions and the old wiki-imported pages which were sorting them out in to various 'categories'.

We need a better way to continue to categorize methods and add custom supplementary information while using auto-generation as the primary source of content.

Describe the solution you'd like

• Consider the benefits/drawbacks of supporting categorization through props or through folder structure
• Implement a way to support supplementary information on specific C# methods via markdown content files

Additional context Assigning myself as this requires changes to the docs core repo

I think it will end up being something like this:

Tried to keep similar structure with sub-actions, so the parameters and value keys work the same. value can then be plugged in automatically for the CPH code example.

Closed now that you can also import shared params from the _parameters partial directory.
