Easier installation of optional dependencies for the marimo editor

[mscolnick]

Description

Easier installation of optional dependencies that enable:

• SQL support (duckdb)
• AI features (openai/anthropic)
• Charting (altair)
• Charting w/ performance (vega-fusion)

Suggested solution

We can re-use the Package installation modal that happens when there are imports that fail. We will also need to make sure the UI is updated appropriately (capabilities is refreshed).
