Update NuGet Icon

[jamesmontemagno]

Hey there! I have worked on some default templates for NuGet icons that you can use. The first will allow you to add any icon or text on top and the second just has a placeholder NuGet icon that could be used. I hope this helps. It is easy to update just via the NuGet website.
