Subject: [PATCH 1/2] Removed pyyaml==6.0 for new workaround after Cython 3.0

After the Changes to Cython 3.0, it has become difficult to build pyyaml < 6.0 wheels. The recommended workaround is having a pre-wheel installation for pyyaml==x, with a pip constraint file having text 'Cython < 3.0' and installing pyyaml==x using pip install command. (Needs a change at the hands on version as well, with additional commands)
