Replace distutils.dir_util.remove_tree() by shutil.rmtree().

[baldurmen]

In Python 3.10 and 3.11, distutils has been formally marked as deprecated. Code that imports distutils will no longer work from Python 3.12.

I'm pretty sure distutils.dir_util.remove_tree() and shutil.rmtree() do the same exact same thing and this should fix the issue :)
