Borders not shown for image nodes

• Ubuntu 20.04 LTS

Screenshots

Sirius Desktop (there are borders with style customizations)

Sirius Web (I manually had to add a border to the icon image)

Steps to reproduce

Add a border for the bordered node.

Expected behavior

The border is shown.

It would be great if it also handled all border colors that Sirius Desktop handles, as well as style customizations for the border color.

Actual behavior

The border is not shown.

Actually, this does not seem related to the fact that these are border nodes. I can reprroduce it with plain nodes:

Here the node at the top and its border node are plain nodes and their border size and color is correctly represented.
At the bottom, both the image node and its own border node have the same border configurations as the ones above, but neither have a visible border.

The issue is that the border (size, style, color) is completely ignored for image nodes (whether they are border nodes or not):

• org.eclipse.sirius.components.compatibility.diagrams.WorkspaceImageDescriptionConverter does not consider the border-related properties of the WorkspaceImageDescription (color, line style, size computation expression);
• org.eclipse.sirius.components.diagrams.ImageNodeStyle does not support them anyway;
• the corresponding types (and code) on the frontend also needs to be made aware of these properties.
