F-Droid listing (icon, feature graphic, screenshots, description) is outdated

[leoheitmannruiz]

• This is not a feature request (existing functionality does not work, not missing functionality).
  I will request features on forum or via support.
• I've searched and did not find a similar issue.

Describe the bug
The resources at https://f-droid.org/packages/de.tutao.tutanota/, which are pulled from https://github.com/tutao/tutanota/tree/master/app-android/app/src/main/play/listings, are outdated.

To Reproduce

1. See https://f-droid.org/packages/de.tutao.tutanota/ (note that the feature graphic is not displayed here, but in the F-Droid client)

Expected behavior
I expect the resources to be the same as the ones used for Google Play at https://play.google.com/store/apps/details?id=de.tutao.tutanota.
