Packages - Modal - Empty buttons

[umbrabot]

Open package (Umbraco forms) - Print screens are reporting as Empty buttons

Steps to replicate:

1. Navigate to packages section
2. Open a package (e.g. Umbraco forms)
3. View the print modals (near the bottom of the page)
4. Each are empty buttons

Issue: Empty button: A button is empty or has no value text

Why it matters: When navigating to a button, descriptive text must be presented to screen reader users to indicate the function of the button.

How to fix: Place text content within the element or give the element a value attribute.

PR for this one here https://github.com/umbraco/Umbraco-CMS/pull/13114 - Changed the button back to an anchor tag with a valid ng-src attribute pointing at the larger image as one would usually do implementing lightboxes on regular websites.
