Pin the Python version to 3.11, since OpenAssetIO is currently
unavailable on PyPI for 3.12 (i.e. only currently supports VFX Reference
Platform CY23/24).
Checkout ComfyUI and add to PYTHONPATH for tests, since we make use of
its internal utility libraries. We also make use of some of the
dependencies of ComfyUI (e.g. numpy), so install ComfyUI's dependencies
into the environment.
