Updated misleading documentation

[DrJohnT]

Note that the images for Visual Studio Test task are incorrect. The Test filter MUST be TestCategory and NOT Category. These should be updated along with the text

I am not sure if we have the same understanding what VSTest is.
For me, it is the platform for test execution in .NET. All Testframeworks (xUnit, NUnit, MSTest, SpecFlow+ Runner) are integrated into it. So having it on the same list as them, makes no sense for me.
For me it can only be VSTest+NUnit, VSTest+xUnit, etc. There is no VSTest for me alone.

AFAIK it passes the filters through to the test framework which does then the filtering. That's at least how I implemented it in the SpecFlow+ Runner.

What does VSTest mean for you?

My point is that the Azure DevOps screen shots are wrong as using Category=XX DOES NOT WORK!

The word Category should be changed for TestCategory.
The screenshot should look like this:

Examples of using TestCategory (not Category) can be found here https://gasparnagy.com/2016/05/specflow-tips-run-only-specific-scenarios-in-tfsvsts-build/

Documentation for VsTest can be found here https://github.com/microsoft/vstest-docs

The screenshots are from a project that uses xUnit, in which Category works (https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-test#filter-option-details). That is not stated here and should be.

But you did other changes which adds VSTest to some places that I don't understand why.
