Remove .mzp-c-card-small-cta style

[michaelmccombie]

There is a card on the homepage with an underline(on hover) that extends the full width of the card in Firefox. Adding width: -moz-fit-content; should fix this issue

This isn't going to be part of the home page (these card types don't exist any more and have been replaced by the marketing billboards). But we could still either fix the underline, or remove that style entirely.

[alexgibson]

A non-vendor specific fix would also be to use display: inline-block;, as there's no real reason the element needs to be block-level.

@vincejoyiv should we remove this small link style from the cards? (we currently have no design using it, as was a left over from the bedrock card omponent).

[vincejoyiv]

@alexgibson yes, for now. I think as we make these cards more useful in other contexts, we'll find that we need some kind of CTA link. But we can cross that bridge when we get there.
