Automate the Docker container creation and upload to Quay after a new release

[sayalaruano]

Now, we manually update the Docker container and upload it to Quay; it would be good to automate this process with a GitHub action after every release.

Relevant GitHub docs: https://docs.github.com/en/actions/tutorials/publish-packages/publish-docker-images

And the current Docker images and build-push script are available on the nf-core-vuegen repo.

This also affects the VueGen nf-core module, as it uses the containers on Quay.
