Clarify Brand Guidelines for .NET Foundation and Community Usages

Hi!

Love that this repo is out on GitHub and provides a lot of great detail. However, most of the guidance in the brand guidelines PDF seems to be geared as if everything is coming from .NET communications (I assume from the .NET team itself).

It'd be great to have a section/guidance on how to use (or not use) this content with regards to the .NET Foundation or community projects which are .NET based.

E.g. if a project wants to proudly badge themselves as supporting .NET or that a specific feature they support is .NET Standard, how should they go about doing so? Can they just use the .NET Logo or not?

Thanks!
