Hints for qtcreator in main

Warnings

• asv-cid-rdns-contains-hyphen
  org.qt-project.qtcreator.appdata.xml:4 - org.qt-project.qtcreator.desktop
  The component ID contains a hyphen/minus in its domain part. Using a hyphen is strongly discouraged to improve interoperability with other tools such as D-Bus. A good option is to replace any hyphens with underscores (`_`). Hyphens are only allowed in the last segment of a component ID.
• asv-release-time-missing
  org.qt-project.qtcreator.appdata.xml:53 - date
  The release is missing either the `date` (preferred) or the `timestamp` property.
