Build/Test pipeline for Monaco Editor

[rebornix]

Right now we majorly rely on maintainers to do testing and sanity checks before every release manually. Considering that we now support both AMD and ESM and we have 5 built in extensions shipped with Monaco Editor, an automatic build and test pipeline can help us avoid shipping broken bits as much as possible.

• Fetch master from VS Code and build Monaco Editor core from it
  • Throw when build and tree shaking fails
• Test the core and ensure the basic functionalities work

CI configuration is defined in https://github.com/microsoft/monaco-editor/blob/master/.github/workflows/ci.yml

I don't think it'll be too useful for you, but you might be able to take some of my work form https://github.com/orta/make-monaco-builds

@orta thanks, I like the nightly build setup, only one question, it will publish monaco-editor nightly with monaco-editor-core from NPM and TypeScript nightly, right? In my setup, it's the other way around: we bundle monaco-editor-core from vscode master and monaco-typescript from NPM, run tests against it to see if there are any potential bugs.

Shipped.
