Antoine Guenet b822da476e [FIX] website: only apply default lazy loading on images in frontend
The `loading="lazy"` attribute was set by default on all images but this
affected the `mass_mailing` module as well while that attribute doesn't
work in emails and can cause some issues in edition.
One known such issue this addresses is to be reproduced as follows:
1. Create a new mail
2. Drop the "cover" snippet
It has height 0 so it won't load until another snippet (with a non-zero
height) is dropped.
