Pushing YYYY.MM tags again (#158)

* Pushing YYYY.MM tags again

It appears this broke with the move to multi-arch workflow. I updated the syntax to fix this issue based on [some docker/metadata-action documentation](https://github.com/docker/metadata-action?tab=readme-ov-file#major-version-zero). I think the limitation might be the Python script which generates this.
