The Great Cleanup 🧽

Problem

The build system used in this repository suffers from bit-rot: it uses tools which have been deprecated and for which it's really hard to find documentation, most dependencies are not maintained and broken, the standards used are outdated and completely different from everything I've seen...

This results in a system which is really hard to maintain and build. As an example, when I started working with neo-mon it took me a whole day to get it to build and when preparing this PR I had a lot of problems finding documentation that was out-dated enough (in one instance I had to hunt down the correct version of the documentation of a package through git history and build it myself to see it). Furthermore, I have to be extremely cautious when modifying everything in order to avoid breaking anything.

Solution

This PRs solves that by simplifying the whole build process to the extreme, making it only depend on bash and npm (which installs only a single dependency!) and removing a lot of stuff which becomes unneeded.

Drawbacks

Because of the dependency on bash and several nix tools it will be much harder to build on Windows, nevertheless build.sh is easy to read and I believe it's still an improvement over the current build system.

It also removes the linters.

Extra

This PR also updates the CI action used for gh-pages deployment.
