We should default to making code blocks editable: this ensures
consistent syntax highlighting (see #343 ) and it allows the instructor

anyhow: Remove ReadUsernameError::IoError
...
As far as I understand, the example with the `anyhow` example
does not use its special `IoError` anymore, unlike the previous
example with just `thiserror`.
I think this should be made clear. I considered just adding a
`// Now unused` comment, but I think ti's clearer to just remove
the unused code.
