Use picture info in nuxeo-picture-formats

picture:views height and width is recorded twice. Under certain conditions the height and width shown in the info object can differ from the 'other' dimensions. Update https://github.com/nuxeo/nuxeo-web-ui/blob/master/addons/nuxeo-dam/elements/nuxeo-picture-formats.js#L84 so that picture:views/info/height and picture:views/info/width is used instead of picture:views/height and picture:views/width

Changing this line in the getAdditionalFormats function should do it:

 dimensions: `${view.info.width} x ${view.info.height}`,
