TrxReport Capability Documentation

[thomhurst]

Implementing support for Trx involves more than just bringing in the TrxReport extensions package.

I believe I've worked it out myself, but it'd be useful to have it documented officially, as I couldn't find any.

You're right we should add some documentation here https://learn.microsoft.com/en-us/dotnet/core/testing/unit-testing-platform-extensions-test-reports#visual-studio-test-reports

I think this is more of a technical documentation for framework authors, so we should start with doc on our repo.

@MarcoRossignoli we should ask @IEvangelist if we can start moving the technical doc under the official doc repo so we have something unified.

Move what, where?

Sorry :) We started to write some technical documentation (for framework and extensions authors) around our new testing platform. At the moment this tech doc, lives in this repo https://github.com/microsoft/testfx/blob/main/docs/testingplatform/Index.md but I think it'd be better overall if all the doc was available at the same location (with some structure to split "normal user" from "extension builder user").
