[Snap Store] Display submitted date, updated date, changelog, expandable product images for all applications

Snap Store applications.

- Display application submitted date to store
(this's additional details but good to include)

- Display application last updated date
(Currently this display only for several applications; idk why)

- Changelog
(That's nice, if application maintainer able to publish as google play, windows store)

- Expandable product images
(Currently we cannot expand product images to see properly and some are even unable to recognize well due small letters, icons under default size) Check google play store, windows store for that.

- Set minimum quality for upload product images.
(Currently some applications pages have very low quality images).
