Must use typescript grammar to ensure GitHub compatibility

Describe the bug

I am working on getting GitHub support for highlighting edge files. GitHub uses the atom javascript textmate grammar which does not include #expression in it's repository causing the highlighting to be broken for highlighting powered by atom's javascript grammar.

You can see how github will highlight edge files using this preview app which also used the atom javascript grammar.

This is how it highlights using source.ts instead

Okay, if I get it right. We have to switch from source.js to source.ts and everything will work fine?

Does this change has to be made within this repo? Or can we just use source.ts inside the source code shared with Github linguist?

[evoactivity]

It must be made in this repo. Linguist uses this repository as a submodule to pull in the grammar so it will be automatically updated as changes are made to the grammar without us needing to submit patches back to linguist.

Cool. Makes sense
