Requires docker login?

[altjx]

While running the action-clean github action, I noticed that it failed because I needed to login to docker. Is this truly the case? I've run it plenty of times before without logging into docker, so it just confused me and caught me off guard. I'm logging into docker for other jobs, but I wasn't aware of this requirement.

Btw really love this action -- was a PITA getting "permission" errors beforehand.
