[FIX] web_editor: allow html widget for html fields
[FIX] web_editor: allow html widget for html fields

Before this commit, it was not possible to set the 'html' widget
for a field in Studio.

Even if this is the default widget for the form view, it not the
case for the kanban view. You need to precise each widget you
want to use (for performance reasons).
