details-page: Update design of the "page_failed" AdwStatusPage

Use "dialog-warning-symbolic" as the icon. Also, add a title and a description to the page to detail what happened instead of showing a generic message.

I copied the "Before" screenshot from !1852 (merged) and made the "After" screenshot in Workbench, because triggering this status page is a little tricky.
