Move scraper to subfolder and initialize new Vue.js project

[dan-niles]

Changes:

• Scraper (Python code) has been moved to the scraper subfolder
• Vue.JS is now used as main UI framework; all of its code is in the zimui subfolder; it is rendered with Vite to produce a static website.
• Vuetify has been installed and setup
• QA and Tests workflows have been adapted
  • to the new folder structure
  • to also QA and Test the Vue.JS part
• precommit hooks have been configured for the Vue.JS part
• Dockerfile has been adapted to first build the Vue.JS part in a dedicated stage and then embed the generated files into the final Python-based image
• New CLI argument --zimui-dist has been added to specify the folder where zimui has been built
• Switched to "on-the-fly" items addition to the ZIM by using Creator instead of make_zim_file

Disclaimer: From this point, the scraper is intentionally quite broken in the sense that it does not create a usable ZIM anymore since we had to comment out significant code portions to move to the new ZIM UI and Creator.

Closes #205

Few comments inline.

Some other points:

• you must mention in your issue that:
  • you've started the move to "on-the-fly" items addition to the ZIM (I've just opened Use scraperlib & pylibzim properly - add items to the ZIM "on the fly" #209 which is about it, the move is not yet finished since you have to fix all commented code)
  • from this point, the scraper is intentionally quite broken in the sense that it does not create a usable ZIM anymore since we had to comment out significant code portions to move to the new ZIM ui and creator
• add a disclaimer at the beginning of README.md explaining that for now the scraper is undergoing significant rework for 3.0 release and the main branch is not very stable ; v2 branch is available (I just created it) should an important patch be pushed before v3 release
• do we really need to keep the zimui/README.md, it does not provide much value from my PoV ?

We should also open new issues to not forget that we have to (no need to do it in current PR, can be tackled afterwards):

• add a CONTRIBUTING.md at the root of the project explaining how to develop the zimui, just like we have at https://github.com/openzim/kolibri/blob/new_ui/CONTRIBUTING.md
• fix code coverage upload for Python part ; looking at the CI it looks like it fails to find the coverage report, it is probably broken as well in kolibri ; since we have almost zero test anyway, it is not an urgent problem to solve ^^

Updated the README.md with a disclaimer and removed the README in the zimui folder in 7431881
