Add lightbox for images to provide zoom effect for better visibility

[NiceGuyIT]

Some images are small and hard to read. It would be nice if you could click the image and get a larger image on the screen, possibly with zoom for very large images.

The Material for mkdocs suggests the glightbox plugin. There's also lightgallery-markdown and possibly others.

Sounds like a good idea, I'll have a look.

Feel free to try yourself too!
