Deprecate the documenter keyword argument.

Instead of passing documenter=(true|false) to Literate.markdown
pass flavor = DocumenterFlavor() or flavor = CommonMarkFlavor()
as appropriate. For Literate.(notebook|script) it is not needed
anymore either, since removal of at-ref and at-id are now happening
unconditionally.
