scratch-api/scratch-cli#3

I'm making docs on how this would work here. I'm planning it to be built somewhat differently to this scratch-cli, e.g. directly using rich's markup instead of using markdown.

I would also recommend that the formatting methods be implemented within scratchattach itself instead of the CLI.
