Enhancement: Improving Image resulting code in the Markdown parsing library

### Impacted plugin

None / Other

### What

Images doesn't have any width limitations

### How

We have introduced the markdown parsing library in our synced handbooks (as part of the whole integration), and it seems that the resulting HTML for the images, when the images are too big, tend to break the page

Example

Ideally, the markdown parser should add at least a `max-width:100%` and maybe, a `object-fit:contain` to avoid this unnecessary overflows.

Start by locating the Markdown parsing entry point that produces the shown img HTML and inspect how image attributes and styling are assembled. Compare the current output with the reported oversized-image example; done means rendered images no longer overflow their container, using the requested max-width behavior and evaluating object-fit containment.
