Fixes formatting for docs
Fixes formatting for docs

Unfortunately, three tildes works as "cross-out" in GFM, and not as "code-sample".
As a result, this was breaking the formatting and layout of the bottom of the page.
To fix this I have simplified the NuGet Package Manager code sample to use the standard GFM "code" convention.
