feat: Warn when named codeblocks lack classes

To both improve debugability when writing scenarios, and also
to protect against future incompatibilities which might occur
if we add more classes which are appropriate for named code
blocks, we require that named blocks have one of `file` or `example`
as classes or else we warn.
