Change pre commit hook format

[kilian-goetz]

Summary

Husky reformat code during commit. Currently, indentation is only two space. I think it could be better to change for 4 space like a real tabulation.

Motivation

Change for 4 space will render code more readable, and it will respect global formatting of 4 space for one tabulation.

Implementation

In .prettierrc.json file, add only tabWidth:

{
    "bracketSpacing": false,
    "tabWidth": 4
}

Well, if you take a look at the eslint's config file, you'll see that it becomes quite unreadable with a 4 space indentation. In general, when you have complex JSX elements description in your code, an indentation of 4 spaces starts to take too much place on the screen ...

This question is a point of view. Personally, I found more readable 4 space in JSX than 2. Moreover, it's a global norm of 4 space for one tabulation…
