DOC: Update the tutorials

[benoit9126]

I updated the tutorials using the last version of RLF. I also add some README files

This is blocked on the current changes that break the API, converted to draft.

I updated the tutorials repository. I suggest that we remove the tutorials from this repository and link to the other repository instead when we make it public after the next release.

I know I advocated for including the tutorials here before but there are things that I didn't consider before that would affect beginners, namely:

• Problems with git lfs on Windows as this repository uses lfs because it includes large pdf files. I only noticed these problems recently when working on another project on Windows with Louise
• Downloading the tutorials as a zip file as an alternative for people who don't have git installed (mainly Windows users :/). This is what most users comming from https://github.com/Team-Nando/Tutorial-DERHostingCapacity-0-dss_python?tab=readme-ov-file#run-part-0 will be doing
• Using the wrong rlf if their python picked up the local folder instead of the site-packages version

I'll send a PR to remove the tutorials from here if there are no objections to the proposal @benoit9126.
