[WIP] Include server in VSCode client

[skovhus]

This is a work in progress PR trying to remove the manual step of installing the server.

It currently fails when running locally (Launch Client) with:

Error: The module '/Users/kenneth/git/bash-language-server/vscode-client/node_modules/tree-sitter/build/Release/tree_sitter_runtime_binding.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 48. This version of Node.js requires
NODE_MODULE_VERSION 54. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or`npm install`).

The reason seems to be that the dependencies are installed locally with yarn/npm for my machine/node version, but once I start the client with Launch Client it runs inside Electron.

Things to investigate: https://electronjs.org/docs/tutorial/using-native-node-modules

It might be that this works when installing the extension through VSCode.

@skovhus It might be interesting to try to package and install it manually without publishing it to the store :)

cd vscode-client && vsce package
code --install-extension <path to package.vix>

(by the way if that's a useful way to debug something it might be nice to add it to the docs somewhere 😉)
