Original PR

#842

Things done

• Inside test/utils.tsx extracted a render function with a wrapper with Lingui, in this way we don't need to wrap any render function on every test, also exports every function of testing library native so you could use that file for every test
• Removed the _.(t) function because it was useless, Lingui v3 is use the macro functions, there's no need to complex everything. https://lingui.js.org/ref/macro.html#examples-of-js-macros. IN some cases you need to format currencies, numbers, or dates giving a locale, Lingui also exports date, and number macros but those ones are extracted from the @lingui/core library. **I've remember this because I saw hard-written dates formatted to iso but could be good to format them using the locale instead of the iso... **
• Added lingui.config.js with a typedef for checking that the config is valid ;)
• Modified the add new locale and add new translation readmes to match latest lingui version
• Also i saw that you use a lot unicode chars to give spaces to things, in Lingui v3 we strip this characters so just use html entities or basic templating

Huge ! n'oublie pas de faire un message aux PO pour qu'ils fassent attention aux traductions.

Je pense qu'il serait même préférable de demander une repasse sur les traductions lors de la prochaine session globale de test
