docs(readme): Update README.md

[sylvaincom]

WIP, according to #411

[rouk1]

IMHO we miss the pip install line in the quickstart section.

What about adding gif to the README ?
This gif could be a notebook side by side with a skore ui demonstarting the UI.
I personally tend to read longer if I see images.

For inspiration see zoxide's readme which demonstartes the tool in a few seconds using a gif.
More inspiration in the awesome readme repo.

For a first iteration, it looks good to me, what do you think?

[tuscland]

Very nice improvement

@sylvaincom this snippet will fix the README.md for you (there is something wrong).

python -m pip install --upgrade pip               
python -m pip install --upgrade pre-commit        
                                                  
pre-commit run --all-files check-yaml             
pre-commit run --all-files check-toml             
pre-commit run --all-files check-added-large-files
pre-commit run --all-files check-merge-conflict   
pre-commit run --all-files detect-private-key     
pre-commit run --all-files end-of-file-fixer      
pre-commit run --all-files trailing-whitespace    
pre-commit run --all-files typos

To go forward I'll approve this and create an dedicated issue for the notebook pre commit hook.

IMHO readme assets should not be hosted outside of the repo.
