Undockerize local & CI site builds

[rossturk]

While I was working on #629, @potiuk recommended moving away from Docker for the functions of site.sh.

This updates the shell script to remove all of the Docker command execution, and makes changes throughout to remove hardcoded paths. It updates the GitHub workflow to install Hugo and Node, and it adds a few steps to the contributor docs to show users how to do the same.

As a side-effect, this makes site.sh and its related tools/processes work on ARM-based macOS machines.

Noting that site.sh is to be replaced with Python version
#623

[potiuk]

Yeah. As with my intuition - since we are really relying on very simple and straightforward set of dependencies, the need to use docker is limited here and relying on node and hugo installed locally makes perfect sense. This makes things simpler.

@eladkal yeah. We discussed it and I think it is something @Bowrna should adapt in her changes (and it will make it actually a bit easier to test)

[potiuk]

I think conflict needs resolving :)

@potiuk ok! cleanup is done now, thanks for merging that other PR!

Fingers crossed. The GitHub workflow does different stuff on merge to main, hope there aren't surprises.

Will there be any surprises, we will fix them :)

BTW. The way I test merges to main (airlfow has VASTLY different workflow when merging) is git push -f my_fork my_branch:main -> this will push your branch as main (i..e. same as merge) and if you configure the same SECRETS that we have in "apache" in your fork + make sure that the "bucket" name is configurable from secret (I think it is) you can test merge workflow in your own fork with relative ease

Merge running https://github.com/apache/airflow-site/actions/runs/2657942667 , let's see.

All good. Build is Green, the website did not blow up :) 👍

@rossturk I get an error saying yarn command not found in my local machine( m1 mac os). Am I missing executing any specific step in documentation?

[potiuk]

yep. You need yarn to be installed
