[FIX] web_editor, website: adapt hover animations to shape availability

Steps to reproduce:

- Go to website in "Edit" mode (on a blog post page).
- Select one of the default images in the blog content.
- Click on the "Animation" option and select "On Hover" > Traceback!

Starting from [1], the "On hover" image animation was implemented to be
able to pick an animation that triggers when hovering an image.

This feature is setting a default "Square" shape (required for the
hover effects to work) on the target. Which means that an error can
always occur if the "On Hover" animation option is available while the
targeted image is not linked to an attachment and can't support image
shapes (which is the case here).

The goal of this commit is to fix this issue by only allowing the
"On Hover" animations when it's possible to apply shapes to the image.
