This is a request to add the Fluent language to the built-in syntax highlighting.
Example:
```fluent # Simple things are simple. hello-user = Hello, {$userName}! # Complex things are possible. shared-photos = {$userName} {$photoCount -> [one] added a new photo *[other] added {$photoCount} new photos } to {$userGender -> [male] his stream [female] her stream *[other] their stream } ```
