feat: Start associating packaging shapes images in the taxonomy

[teolemon]

What

• Start associating packaging shapes images in the taxonomy
• Sometimes we have several shapes per entry:
  • in that case I've tried to take the most representative
  • in some cases, create subentries that are currently commented out
• I have added suggested materials per the official CITEO guidelines
  • They could be displayed on top of material suggestion lists, and possibly used for potential Robotoff questions

It's a great idea to add images for each packaging shape.

Regarding the format of the property:

• we should use image:xx: instead of image:en: so that the images apply to all languages
• we should move the CITEO images to from html/images/icons/packaging-shapes/ to html/images/icons/packaging-shapes/citeo/ so that we can easily add other images

so the format should be something like:

image:xx:/images/icons/packaging-shapes/citeo/brique-2.svg

Regarding the content:

We may not need to add all Citeo icons as entries in the taxonomy. If we do add them, then we should have an English names for them. It might be useful to have all of them at some point (e.g. to recognize them, even though my understanding is that they will go away in France).

The focus at first should be on getting an image for all existing entries (or their parents, we can inherit the property), so that we can use them in the packaging edit interface and in knowledge panels etc.
e.g. We can assign the most generic looking bottle image to en:bottle.

@stephanegigandet 👍

• fixed the xx lang code
• moved the images to a dedicated CITEO directory
• everything remains commented out for the time being, and we can uncomment as we feel confortable

We can merge as-is, we can decide on the formatting, add image paths etc. after.
