CI should check the dev container setup

[Martin521]

There should be a check in CI that building in a dev container succeeds.
So that authors changing global.json are reminded of the necessary changes to .devcontainer/devcontainer.json.

That particular approach won't work. All CI which builds code should run in azdo.

Currently devcontainer build is broken, the SDK requested by global.json is not installed.
I figure there is no easy fix because a devcontainer image is available only for the latest version (9.0.200), and global.json currently still needs to be on 9.0.103, is that correct?

Devcontainer should be updated together with global.json. If it wasn't, it was a mistake. They simply need to be in sync.
