Breaking change: Update FrameworkName to ".NET"

RuntimeInformation.FrameworkDescription(String) returns ".NET" instead of ".NET Core".

Version introduced

.NET 5

Old behavior

RuntimeInformation.FrameworkDescription(String) returned ".NET Core" as part of the description string, e.g.: ".NET Core 3.1.1".

New behavior

RuntimeInformation.FrameworkDescription(String) returns ".NET" as part of the description string, e.g.: ".NET 5.0.0".

Reason for change

With .NET 5, netcoreapp is replaced by net as the short target framework moniker and with that the framework's description is updated as well. The change is cosmetic as the FrameworkName isn't encoded anywhere else than in the RuntimeInformation.FrameworkDescription(String) property.

Recommended action

Alter the code that searches for ".NET Core" in the string returned by the API to ".NET".
