Dependencies incomplete in development-guide.md

Hi there,

Started looking at building this myself on WSL after attempting to install with npm i -g bash-language-server failed.

It may be academic, but in the build process I had to work out for myself that I would need node (v6 or greater), make and g++ installed. Probably not unique to WSL, but I'm a bit of a novice when it comes to building things that aren't .NET 😉

@PromoFaux I'd be happy to accept a PR with an updated set of prerequisites 👍

No problem, can do! Was going to do it anyway, but just wanted to make sure I wasn't being an idiot first 😂
