correct the casing of Method enums in RestSharp snippets (#366)

Ensure that code snippets use enum members that are pascal cased and
not upper cased. For example use `Method.Get` instead of `Method.GET` to
ensure the snippets can compile.

fixes #365

use `var` for return "type" of RestSharp request response

The type `IRestResponse` doesn't exist in latest client (version 112)

fixes #367
