Bump TSServer & Theia Version

[mattlyons0]

New versions of TSServer when paired with Theia's language server include some very useful features (most notably it now seems to download types for node packages in the background now).

I've tested this throughout various JS repos and have not noticed any regressions.

The reason for the Theia (typescript-language-server) semvar major bump is because the package bumped monaco-languageclient which now is written in ES6.

This fixes #158.
This affects #144 by making its impact less widespread (any package with typings will no longer show the warning).

@damieng, @50Wliu, would love to have this one out soon. I see errors in Node.js that I don't see in VSCode that would be solved with this PR.

And what are you waiting for?

And also why not to use project based typescript version?

I left GitHub over two years ago and stopped working on Atom and Atom IDE. While I can no longer speak for GitHub I think the fact they announced they were ceasing work on Atom IDE at the end of 2018 and there's not been any activity at all on this repo in over a year should tell you why.

@damieng I understand that you're not involved with atom development at the moment. Is there anyone else you can pass the baton to? There are still plenty of Atom users who would love to see this relatively straightforward PR land and release.

pinging @darangi (sorry if i'm pinging too much. - No one at https://github.com/atom/ide-typescript/graphs/contributors contributes to atom today, but since you're under https://github.com/orgs/atom/people you probably have access to merge this pr)

[damieng]

@icecream17 there is an alternative community-maintained package over at https://github.com/atom-community/atom-ide-javascript you might have more success with.
