Fix description in the module openy_media_image

There is a module openy_media_image. This module has an empty description in configuration files(14 files).

We need to add a description.

See for details
https://github.com/ymcatwincities/openy/blob/8.x-1.x/modules/openy_featu...
and many other files in the same module

We need to understand what each field do and provide the corresponding description.
