fix: Change the TEMP folder for Gradle tests to home for Windows

[lucashuy]

Issue #, if available:
None.

Description of changes:
Something changed within the runner environment, causing all Java Gradle tests to fail with the following error message:

 * What went wrong:

Gradle could not start your build.
> Could not create service of type BuildLifecycleController using ServicesProvider.createBuildLifecycleController().
   > Could not create service of type BuildModelController using VintageBuildControllerProvider.createBuildModelController().
      > Could not create service of type OutputFilesRepository using ExecutionBuildServices.createOutputFilesRepository().
         > java.io.IOException: Cannot delete file: C:\Users\RUNNER~1\AppData\Local\Temp\tmpale85rhe\gradle-cache\buildOutputCleanup\buildOutputCleanup.lock

I still don't know why this is the case, but we can update the folder we point Gradle to, to a the home directory of the runner as a workaround.

Do we need to create another folder under userprofile so that test files won't clash with each other?

Shouldn't need to, the tempfile library creates unique folder names each time that shouldn't clash with anything in the existing directory. We'll probably want to create a subfolder if this was a normal test, for a normal user just to keep things nice and tidy. But since this is the CI runner, I'm sure the runner won't mind
