caption spacing update

[mjabbink]

In one of the caption (below) there is an extra 4px or so under the image which is adding additional space above caption. This extra space under image should be removed.

@vpicone can this be closed w/ your latest caption fix?

Ah, looks like this issue is coming from the image. I thought this was just happening in the IDL site and had opened a PR there in December (https://github.com/jnm2377/design-language-website/blob/3649a124dc933f594985d85cb6257bca86333676/src/styles/_images.scss#L14)

Will add the display: block for images in Gatsby as well. I think that should do it.

fyi, I think the problem with those images in the IDL site is that they aren't in a row, so it's not receiving the styles I added. It seems some of the images are wrapped in a row container and some aren't, so it probably would have been better to just make the img styles as generic as possible. Either way, I can add them to the gatsby theme instead.

The first image sample is from Gatsby them site not just IDL site. It is happening across the them sites.
