Given a line like FROM alpine:3.16, we should show when the image was last pushed as an inlay hint to help nudge/remind the user if it seems like it is pretty old.

We will not render anything for the following cases:

• FROM alpine will be ignored as latest is dynamic and hopefully people are not using latest to begin with
• images from other registry, we will support Docker Hub only at the moment
• images behind authentication, since the Docker Language Server has no authentication information right now we cannot query the Hub API for these images
• images with a digest SHA may be outdated and not included in the response so it is unclear when it was last pushed
