Scrub references to WebRequest

[scalablecory]

There are some places within docs that discuss WebRequest as if it is a current solution e.g. https://docs.microsoft.com/en-us/dotnet/api/system.net?view=net-6.0

We should search all docs and ensure we don't present WebRequest or WebClient as a recommended solution. Instead docs should just be factual about functionality and how to use the APIs.
