feat: add skipper-go integration card (testing/Testify/Ginkgo)

Replaces the coming-soon placeholder with a full card linking to the
GitHub repo. Also fixes card layout: replace flex:1 on card-frameworks
with margin-top:auto on card-link so framework badges stay compact
and the link always anchors to the card bottom regardless of badge count.
