Subject: Add CI logic for finding missing translations (#608)

* build: add script to get missing keys per language

* fix: typo

* fix: check arguments before launching script

* feat: script can be run with language argument

* docs: add readme

* fix: remove multiple spaces while searching for translations

* build: add translations check CI

* refactor: put translation job alongside encoding job

* feat: add unicode characters because why not

* build: exit with an error code if some translations are missing

* build: exit using process.exit

* feat: CI should continue running with missing translations

* build: use actions/checkout v3

* refactor: put build directory into .github directory

+# Finding missing translations
+
+This package contains a script that detects missing translation keys in Titanfall2 translation files contained in this repository (in the `Northstar.Client/mod/resource` folder).
+
+It uses english translations file as reference.
+
+You have to launch it **from the repository root folder**:
+```shell
+node .github/build/find-missing-translations.js
+```
+The script will then list all missing translations for all supported languages.
+
+If you want to display missing keys for a given language, just add it as an argument:
+```shell
+node .github/build/find-missing-translations.js french
+```
+
+Here's the list of supported languages: 
+* english
+* french
+* german
+* italian
+* japanese
+* mspanish
+* portuguese
+* russian
+* spanish
+* tchinese
