Subject: [PATCH] workflows/docker: continue to deploy `master` images

I noticed that `master` images have not been updated since #18912:

    $ docker run --pull=always --rm -it homebrew/brew:master brew --version
    master: Pulling from homebrew/brew
    Digest: sha256:3812ffd9b728ce3d96a2a362ef33bed420d1dc73c7d96c93a8f8d2d4f10e6281
    Status: Image is up to date for homebrew/brew:master
    Homebrew 4.4.11-6-geae8d1b
    Homebrew/homebrew-core (git revision 9610909d254; last commit 2024-12-10)

That is due to images no longer being built on `master` pushes. This
change restores the previous behaviour.
