Hints for gnome-firmware in main

Hints

• asv-description-first-para-too-short
  :16 - Update, reinstall and downgrade firmware on devices supported by fwupd.
  The first `description/p` paragraph of this component might be too short (< 80 characters). Please consider starting with a longer paragraph to improve how the description looks like in software centers and to provide more detailed information on this component immediately in the first paragraph.
• asv-url-not-secure
  :63 - http://www.gnome.org/friends/
  Consider using a secure (HTTPS) URL for this web link.
• asv-desktop-app-launchable-omitted
  -
  This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that this application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
