Update App Store Media for v1.1.0

[andrewtavis]

The issue is to update the App Store images and videos before the v1.1.0 release of Scribe.

The images will need to be changed to reflect new updates. Specifically the languages image for each needs to show all six of the languages that will be included in v1.1.0. The data standards image should also be removed as this doesn't seem to be important in hindsight (this has already been finished in be001d3).

The videos for the App Store also need a many edits. Specifically, three videos is too many. The full video needs to be edited down to a less than a minute so that it can fit into two videos.

The app description and keywords should also be updated.
