Add Typescript language file
Typescript is a superset of Javascript, with a file extension of .ts. I noticed there is no typescript language file, so I copied the javascript one and updated it to include the .ts extension. That file is attached. It doesn't add support for any typescript-specific language features, but I'm more concerned with getting something working than having it be perfect. It can be improved over time if people are interested.
Alternatively, it would be fine with me if we just add support for .ts extensions to the existing javascript language spec, but there might be people that want separate language options in GNOME Builder, which is only possible with separate .lang files.
