Langium project generator including TypeScript LSP plugin.

[trusktr]

It would be sweet if the generator could include a mode where it not only bootstraps a standalone LSP extension for VS Code, but also a TypeScript LSP plugin. This would be useful for adding syntax and type checking overlaid on TypeScript. For example, someone may want to add additional syntax checking inside of html`<div />` template strings, etc, and would want to connect it with TypeScript awareness.

Another idea is adding additional type checks to TypeScript itself. For example int or float types that are aliased to number, but the TS LSP plugin can provide additional checks that validate if an int is being assigned to an int parameter, etc.

I'm going to try making a TS LSP plugin myself sometime soon, can can help with this if someone else hasn't gotten to it yet.

We're currently in the process of refactoring our yeoman generator, see #954. I believe after that, the package would be in good shape to also support such a setup 👍
