Docker tries interactive login

[timfallmk]

Currently the docker cli tries to login in interactively, despite https://github.com/machine-learning-apps/gpr-docker-publish/blob/master/entrypoint.sh#L37

This fails because the shell is not a TTY. Notably, the failure is non-fatal and the workflow continues on (but no upload occurs).

Workflow step: https://github.com/ksync/ksync/blob/master/.github/workflows/publish.yml#L39-L48

Build output:
