[FIX] website_forum: show normal image modal in forum

In #67893 the image icon was removed, but it contradicts the interface
and made a feature that was working for employee less available.

Since saas-12.3, we always use the full media dialog when showing the
editor on the forum so we could not add an image with the image icon if
were not an employee.

Before saas-12.3, the original summernote image dialog was shown for
everyone but website editor that saw the full media dialog (beecause we
are using the same editor to do both things).

With this change, we always have the original dialog in the forum
message editor thanks to a new option "disableFullMediaDialog".
