Package updates

[EvanHerman]

I had to remove a few packages that hadn't been updated in a while, and replaced them with more recently updated files. I also regenerated the css files to leverage the newer version of autoprefixer, and regenerated the minified image files.

Theme check is now failing because it's throwing an error for the unsplashed image that we had been grandfathered in and allowed to use.

Note

• [x] The theme-check build is currently failing and is being investigated.
• [x] The CSS source maps should not generate at all. Currently, they are generated and appended to the bottom of the CSS files.

Good job! Would that change be also needed in all of the other primer repos or this one covers them all?

@olafleur-godaddy Yeah, it looks like we're going to have to make similar updates to the packages in the other child themes.
