Note about using .NET Core 3.1.401 or .NET 5 Preview 8 SDKs on Mono platforms

Because of the new minimum MSBuild version requirement of these new SDKs, it will be necessary to use the Mono packaged with the C# extension. The meaning of "omnisharp.useGlobalMono" has change to "never", this forces the use of the included Mono. To use your system
install of Mono set the value to "always" although it may not be compatible with newer SDKs.
