Hints for file-roller in main

Warnings

• asv-releases-not-in-order
  org.gnome.FileRoller.appdata.xml - 43.0 << 43.alpha
  The releases are not sorted in a latest to oldest version order. This is required as some tools will assume that the latest version is always at the top. Sorting releases also increases overall readability of the metainfo file.
• translations-not-found
  Unable to add languages information, even though a translation tag was present in the MetaInfo file. Please check that its value is set correctly, and all locale files are placed in the right directories (e.g. /usr/share/locale/*/LC_MESSAGES/ for Gettext .mo files).
