Bump MSTest and VSTest to latest versions

[Evangelink]

I am using MSTest meta-package that ensure versions of adapter and framework are aligned. It also add MSTest analyzer that could come handy.

Here's the error from the CI:

I'll move forward by closing this one as the SDK one got a little more traction but please let me know if you prefer not to use MSTest.Sdk.
