See if we can fix those things or if it would be on VS Code's side of things:

• Add "quick fix" for when you add a value of invalid type to an argument (e.g. true instead of "true").
  • Currently we just display an warning, but no quick fixes available.
• When adding the wrong arguments on launch.json, squiggles should be red, not yellow (since it's actually an error, not a warning).
