What changes will this PR take into?

This PR aims to fix buildx bug that causes docker build ci to fail. The change is login just before deploying step since Azure login action may change buildx driver.

I don't have an Azure account so I'm not sure it works well. But I've tested Docker Hub and it's ok.

@qsliu2017 I found a similar issue on this: Azure/docker-login#12. As suggested in Azure/docker-login#12 (comment), how about keep using Azure/docker-login@v1, but put it right before the Deploy step?

Thanks for your help, I've updated it.
