Handle VERSION file in pyinstaller hook

[Cleptomania]

When running pyinstaller on Arcade 3.0, the new versioning system causes it to break.

This is because it doesn't catch the VERSION file that is needed by version.py. We should just need to add that file to the datas list within the pyinstaller hook.

This should be good as of #1713 being merged.
