The template no longer use the node image in production

regression from 3c6ebd9

Why is this pull request needed?

#206 changed how the images were built, by removing the node / web image in production and replacing it with NginX.
I didn't make the necessary changes in .github/workflows/publish-image.yaml to reflect this change.

What does this pull request change?

Makes sure the previous web component is removed / renamed in favour of the nginx component.
In principle, the logic for creating the web image was moved to the nginx image. In practice, the web image was renamed, and adjusted slightly, while the old nginx image was removed.

Not sure if I prefer NGIX naming over WEB, I think WEB is clearer. But it looks like this will fix the issue so approved by me

The reason I chose nginx is because I assume it is used as the entry point (the container with exposed ports) to the app when deployed, and I didn't want to make changes there as well.
