"decision guide" for Quarto vs. MyST

[rkurchin]

(somewhat related to #1 but distinct enough that I'm opening this separately)

This is an idea that was kicked around on one of the calls and I wanted to bring it back up here – for folks familiar with notebooks but not specifically with MyST or Quarto, some kind of comparison chart or flowchart guide or something to help them choose between the two would probably be helpful – particularly if they're more comfortable with a particular IDE and/or want specific features that may only be supported in one environment. Some things that come to mind:

• how authoring experience works in various IDE's (I guess we're mainly focusing on VS Code and JupyterLab, or presumably could do all-CLI for the hardcore people)
• how live previewing works (i.e. do I need a separate browser/tab, or can I do it within my IDE?)
• I think also some of the interactivity support is different (like widgets/sliders and stuff)
• where the metadata lives is a bit different too IIRC but that might be more in-the-weeds than necessary

There are probably other distinctions I'm not thinking of that would still be useful to call out.
