docs(readme): separate french and english version of the README

[aikooo7]

Also, I added better descriptions to images

Note:

• All translations were done with https://www.deepl.com/translator and https://chat.openai.com

So feel free to change it if you need to

Closes #26

I separated the commits because I think it is better practice, as you may not just want better image descriptions.
