appview: mark repo cards translate="no"

Repository cards hold user-written handles, names, descriptions and
image references. Browser translators (Chrome, Edge, Safari, and
Firefox once a translation is accepted) honor the translate attribute
on elements below the root, so the card contents stay as written while
the rest of the page translates. This does not suppress the browser's
translate offer, which is a page-level decision driven by language
detection.
