Storybook: Custom icon in the tree

[thany]

Is your feature request related to a problem? Please describe.
I'm making a MDX docs-only story that will act as the homepage of our Storybook instance, and it would be nice to give that item a homepage-worthy icon in the tree.

Describe the solution you'd like
Perhaps in the <Meta> MDX element, add a prop that accepts an SVG path and a colour, that will be passed on to the tree.

Describe alternatives you've considered
I don't think a workaround is possible, because icons are hardcoded in ListItem.tsx.
I've tried to add an emoji into the title of a story, but that doesn't look quite right.

Are you able to assist bring the feature to reality?
Maybe. Depends on the solution we're heading for, should this feature request be approved.

Additional context
Not just homepages, you know. It might be helpful to easily distinguish different component by different icons, or different colours of icons.
