## Description

This PR add the `inlang.config.js` and `@inlang/cli` to Open-Assistant
to solve the issue #3077

With these changes, translators can manage translations in a no-code web
editor and useful linting rules and machine translations can be used
within the editor or via the `@inlang/cli`.

I added a badge with the current translation status and a short
description to the contribution guidelines.

## Further information

To check the status of the translations, exece `npx inlang lint`. Other
useful command like `machine translate` and `open editor` your can find
in the [docs](https://inlang.com/documentation/apps/inlang-cli).

Within this week, the inlang VS code extension should also work ootb for
`i18next` projects and helps extract messages and display inline
annotations.
