Chrome Headless improvements

[cderv]

This is an epic issue to list all that needs to evolve regarding chrome / chromium with Quarto for screenshot for Diagram

• quarto install chromium install a version too old which does not work anymore
• Chrome has evolved into --headless=new and a new chrome-headless-shell (https://developer.chrome.com/blog/chrome-headless-shell)

So we could

• Adapt to --headless=new (does cri port needs update ?)
• Provide a way to quarto install chrome with a pinned chrome version known to work (and prefer that if installed)
• Provide a way to quarto install chrome-headless-shell to latest or pinned version, as it seems to be the best version for PDF printing.

This topic needs to be handled with previous Quarto (possibly only last stable 1.6 and not before) as Chrome does push updated to user, and all chrome after 132 won't work with Quarto without setting QUARTO_CHROMIUM_HEADLESS_MODE=new

For current 1.7 pre-release, maybe this is worth setting QUARTO_CHROMIUM_HEADLESS_MODE=new as a default (instead of false). 🤔 It would be best if we could adapt based on Chrome version used.
