Description

I felt like the default use was like in the readme to use

name: Set up Docker Buildx
uses: docker/setup-buildx-action@v3

And in the readme it says that outputs include imageid. It took me a long time to figure out that doesn't happen if you use buildx. Maybe that should be made more clear in the readme? Or maybe other people knew to expect that?
Thanks!
