Add retries to the docker login action

[fedordikarev]

Ref: https://github.com/neondatabase/cloud/issues/20164

Current problem:

• occasionally we hit 502 from hub.docker.com
• docker/login-action doesn't have retry mechanism
• so we either have to fail the whole Workflow
• or we have to restart whole Workflow

that mechanism at the same time should be conservative, not adding extra unneeded load to DockerHub or another Registry, so for example we shouldn't retry "Bad credentials", we should have timeouts, and reasonable max_attempts
