Update read me to show admonition icons

[Solarer]

Hey, I just found this plugin and had to try all admonitions one by one to see what icons are available. Can you add a second column to your table that shows the resulting icon and box color?

That way we can just look it up and don't have to try them all repeatedly. Thanks!

I had your same problem, so I created a note with all of them:

I am not sure whether they can add the icons/colors to the table (I hope they find a way to do that because it would be very useful, as you wrote), but I hope this image could be useful in the meantime.

Thanks! Yes this picture works very well
