Crop list page
Update the crop list page https://genesys.demo.genesys-pgr.org/c to include one of the crop images from the crop covers gallery.
For each crop, the file repository will contain an image gallery in /crop/{shortName}/covers
. In the API response, include a list of repository images that can be used as the picture in https://material-ui.com/demos/cards/#media.
