Microsoft.CodeAnalysis.NetAnalyzers should only be included when using older SDKs

[egil]

According to the docs at https://github.com/dotnet/roslyn-analyzers, the NetAnalyzers is not needed when we use the .NET5 SDK or later in our projects. As far as my understanding goes, these analyzers will be included just by having .NET5 SDK installed and using that to build with, even if the project we are building has TargetFramework < NET5.

You do not need to manually install this NuGet package to your project if you are using .NET5 SDK or later. These analyzers are enabled by default for projects targeting .NET5 or later. - https://github.com/dotnet/roslyn-analyzers#microsoftcodeanalysisnetanalyzers

DECISION:

Comment out the Microsoft.CodeAnalysis.NetAnalyzers analyzer package in Directory.Build.props and include a comment explaining when to remove the comment (when building with < NET5 SDK).
