SVG tags should be accessible

[wch]

See "Better Accessibility" section in https://www.irigoyen.dev/blog/2021/02/17/stop-using-icon-fonts/

Some other resources:

Maybe also allow users to pass in a title/tooltip/description. This is sort of orthogonal to accessibility per se, but could be handy for tooltips. For example:

icon("question", title = "This thing does x, y, z")
