Make breeze command images more accessible (#26419)

The SVG images embedded via <img> tag are not the best when it comes
to accessibility (even if we have "alt" descriptions). The SVG images
are pre-rendered before displaying in this case and their content is
not readable for visualy impaired people.

We could try to embed the .svg images instead, which makes them better
readable and accessible, but this is a bit complex and would make the
BREEZE.rst huge. We could also embed it via raw html, but GitHub does
not allow this.

Another technique which is recommended is to turn the images
to raw version of the .svg files which (when image is clicked)
render nicely in the browser but the browser actually turns the SVG
source as part of DOM, making the image content accessible to screen
readers.

Another positive aspect of this change is that you can actually
copy&paste the text of the images when you click them.
