Change image push method and set tags correctly

[ATarrio]

• Use the build-push action to actually push images instead of doing it with a shell command
• Use the generated tags to push them to the registries
• Remove step for setting version, we can just use github_ref_name.
• Upgrade some actions versions to newer ones (like checkout which was giving a deprecation warning)
