Explain the name of the repo in the README

[curquiza]

Following the @CaroFG idea, we could explain the name of the repo in the README since some people finds it "offensive"

Here are some explanations Many made on Twitter:

we choose the name of this repository in the same mood as discord or meili, giving the name of the problem we want to solve.
Personally, I don’t feel like it’s an offensive word, but more a funny pun with “char”.
Moreover, other tokenizers don’t always have an understandable name, for instance lindera maintained by @minoru_osuka or even jieba.
I hope my explanation was clear enough and I hope the name will not discourage you to use or even contribute to the project! 😊

Hello @Mount-Blanc
Thanks for beefing volunteer! 😊
You can open a PR, we will review it asap
I would add something I forgot on the issue description: we called it charabia also because it starts with "char" 😇

This is something we would rather not let to the community finally, @CaroFG is indeed the internal Meili people responsible for fixing this issue in the best way!
Sorry again for the confusion.
