add support to mma12, 13 && update deps

[asukaminato0721]

I'm currently working on this. But meet some problems.

1. there are so many dependencies changes... I spent some time updating it...
   1. for example the postinstall in package.json was useless now. https://code.visualstudio.com/updates/v1_36#_splitting-vscode-package-into-typesvscode-and-vscodetest
2. I was developing it on codespace, (So no mma), So is it possible to build it without mma?

currently npm run compile works well. Though there are two //@ts-ignore I can't handle yet.

but when I run npm run build, it says that

> vscode-wl@1.7.3 build
> node build/syntax

node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module '../out/utilities/syntax'

}

so I guess some files are missing during building.

I try to add the |-> in it. But I don't know whether it works.

https://github.com/shigma/vscode-wl/issues/10 this issue could rename 12 -> 13 :)
