Add Screenshots to "Glossary Explanations" Sections

To enhance user understanding and make the "mdanse" documentation more user-friendly, it is beneficial to include screenshots in two critical sections: the "Glossary" and the "Analysis Explanations."

The issue identifies the “Glossary” and “Analysis Explanations” documentation sections but names no files or existing screenshot guidance. Start by locating those sections in the repository and determine which screenshots belong in each; the work is done when both sections include appropriate screenshots.
