testfx Nitpick: `dotnet test` with MTP shows incorrect target framework version

Describe the bug

You can see here that dotnet test is showing this as net48, when it's clearly net472. I don't know if this a difference between "the target framework you built with" vs. "the framework we're running with" (because you could say the same thing for x64 vs. AnyCPU).

This is a nitpick for me. Not sure how important it is for other users.

@MihuBot This is not the same issue, though they are similar.

@nowhnd Could you please have a look at this issue?

Cause for the issue, is the same as what the bot found, just in a different location. The binary dotnet test protocol is reporting the runtime framework rather than the framework of the assembly.

(unlike .NET Core, only 1 installation of .NET Framework can be on the system, so it makes a difference).

https://github.com/microsoft/testfx/blob/main/src/Platform/Microsoft.Testing.Platform/ServerMode/DotnetTest/DotnetTestConnection.cs#L98C75-L98C95

Here the effective runtime is reported, rather than the desired version as specified by TargetFramework attribute on the tested proram/assembly.
