What

Agree what html input types are supported by the govukInput macro. Some, like password seem to work, others like checkbox do not. Others like date appear to work, but it's not clear if we intend that usage.

Then update #2542 (documentation)

Why

It is not clear which types are intended for use in the macro

Would be great to get some guidance on type='date', particularly in light of Dragon NaturallySpeaking's issue with this
