Fix missing MSTestNamespaces.txt in output dir

[gabrielweyer]

MSTestNamespaces.txt should be copied to output directory if we want to use the tool from command line.

Fix #232

Is there any chance of this PR getting merged? I ran into this issue a couple months ago, and finally found this PR that fixed it for me, and I think issue #246 is caused by this as well.

[tiesmaster]

@jaredpar Seeing you've merged #249, now that this project seems alive again, then you might also consider merging this one, since it solves #246, for example.

May I know why this was closed? Looking at src/XUnitConverter/XUnitConverter.csproj it appears the issue is still present.

Looks like GitHub auto-closed it when the branch was renamed. I didn't directly close it. Unfortunately GitHub doesn't let me reopen it. Let me see if I can recreate the PR.

Is it possible you deleted the forked repo? I'm not seeing the branch this PR was based off of anywhere: gabrielweyer:fix-missing-ms-test-namespaces-file. That could be why Github closed the PR. I see others were repointed to main.

[gabrielweyer]

Yes you're right, very likely that I deleted my fork. It wasn't listed in my repositories. I created Pull Request #293 as it seemed easier than attempting to fix this one.
