Embed grammar json in typescript file

[msujew]

To facilitate easy use of the langium package without the need to always copy the grammar.json, we generate a TypeScript file that is easily embedded by webpack.

How shall we handle cases like this, where we change the generated code so a file is no longer generated and used? Shall we include a "clean" step that deletes all files in the target directory? If yes, shall that be opt-in or opt-out via options?

[msujew]

I would say a cleanup step would be opt-out via the langium config options. Especially since the generated directory is usually git ignored, right?

Ok could you create an issue for that?
