Missing figcaption

[jonathantneal]

At http://esri.github.io/calcite-web/examples/core/, I noticed the card examples use a figure element, but do not use a figcaption element even though the classname is caption. Is this on purpose?

<figure class="card-image-wrap">
	<img class="card-image" src="../../assets/img/docs/bridge3.jpg" alt="Bridge Club, 1954">
	<div class="card-image-caption">
		Florida, January 1954
	</div>
</figure>

Would you like a PR to change these to something like the following?

<figure class="card-image-wrap">
	<img class="card-image" src="../../assets/img/docs/bridge3.jpg" alt="Bridge Club, 1954">
	<figcaption class="card-image-caption">
		Florida, January 1954
	</figcaption>
</figure>

@jonathantneal not intentional, that would be a good change.
