feat: add support for Canadian English to VSCode cSpell

The base extension only supports US and UK English; other languages need to be installed as separate extensions. Nixpkgs only has German and French packaged, so I had to pull it myself locally. I think it'd be a good idea for me to submit the other languages up to Nixpkgs at some point in the future.
