Card bug fix

[christiemolloy]

In Core an issue was filed for a bug with the Card component. When an image was added to __head it wouldn't resize properly. To fix this bug we added a new wrapper element called pf-c-card__head-main to wrap the image. We should update React accordingly.

@christiemolloy for some reason I can't find pf-c-card__head-main in https://github.com/patternfly/patternfly-next/blob/master/src/patternfly/components/Card/card.scss

I checked in pf-core version 2.56.1

@boaz0 theres actually no styling associated with the class so that's why it won't show up in card.scss it is just a wrapper element for an image in the card head

I see. so if no class is set to that element, it will be OK, right?
