Feats: Add localization

[thomasync]

Add a global translation for Plane

• [X] A script to help find all the texts to be translated
• [X] A script to reload locales in Plane, so you don't have to run start.sh every time
• [X] Global function to import in every file (I chose to put the function in useMobxStore, as it was already imported in many files
• [X] Add FR Locale
• [X] Resolve the errors that occur when I touch files in web/layouts/*.
• [X] Review each file
• [X] Translate web files
• [ ] Translate space files (not yet planned)

Technical specifications:

The majority of commits are simply the replacement of strings by localized(string), hence the large number of modified files.

Files added with business logic are only :

• web/components/core/localization/*
• web/helpers/localization.helper.ts
• web/store/locale.ts

There are also optional, but very useful, scripts for working on localization:

• scripts/localization.js: Find all untranslated strings in en_US.json and add them. But also add it to all other translations with a null to be edited.
• scripts/reload-locales.sh: Returns modified translations directly, without having to run start.sh again.
