Improved error messages in the UI with clear call-to-action when there are errors

[mscolnick]

Description

Not all our error messages have clear call to actions. These errors exist in frontend/src/components/editor/output/MarimoErrorOutput.tsx

Suggested solution

1. We should improve the messaging, with a CTA
2. Can we improve deep links (linking to cells, or variables, or opening a panel)
3. Can we have auto-fixes or auto-installation or auto-import
4. Can some of the errors be less prominent (either not red or muted red) when they are dependent on another error
