[FIX] web: enable zoom tooltip for ImageField in edit mode

Steps to reproduce
==================

- Set the zoom option on an image field (You can do it with studio
  starting from 16.3)
- Go to a record and hover over the image

=> Nothing happens

Cause of the issue
==================

The tooltip is only displayed in readonly,
but with https://github.com/odoo/odoo/pull/100570 ,
the readonly mode has been removed.
So it only applies for views with the readonly attribute.

Solution
========

Always display the tooltip
