Tests result file cannot be written for Windows packaged apps

[jfversluis]

On the MAUI repo we have this PR: dotnet/maui#29905

The change is simple, bump the xharness version and make the version more central. However, bumping the xharness version breaks our tests on Windows. Before I do into the details: of course Windows is not officially supported and we are using the AndroidApplicationEntryPoint to make it work for Windows, but it has always worked for us... And I think looking at the logs it still mostly works now, except for 1 thing!

We have tests running for unpackaged and packaged apps. The unpackaged apps work, its just the packaged app that doesn't work. And I think even those work, the tests seem to run it just can't write the results file because the file is in use. Which, again, only happens for packaged apps somehow.

If you have any insights, that would be greatly appreciated!
