Fix packaging episode

[ashwinvis]

• Add sphinx-autobuild make livehtml rule
• Test PyPI API token and virtual environment instructions
• By the power of grayskull!

This is important because of two things

1. Username and password authentication does not work in PyPI or Test PyPI anymore. 2FA is mandatory.
2. conda-skeleton does not work with modern Python packages which do not use setup.py
3. grayskull is recommended and it works

I have tested the commands and fixed it.

See:

We recommend Grayskull, a newer alternative to conda-skeleton, to generate conda recipes for PyPI packages. Please check out their project page on GitHub for more information.

https://docs.conda.io/projects/conda-build/en/latest/user-guide/tutorials/build-pkgs-skeleton.html

Starting January 1, 2024, all users must enable 2FA for their PyPI accounts.

PyPI has been on the path of being a fully Two-factor Authenticated service a reality, which began in 2019. Read more about some of the steps taken in recent months:
