Fix Docker publish tag handling

[skokec]

Motivation

• Ensure the Docker publish workflow triggers on tag patterns like v1.0 and avoid publishing multiple semver-derived image tags so only the pushed tag name and latest are published.

Description

• Update on.push.tags in .github/workflows/docker-publish.yml to use v*.* instead of v*.*.* and *.*.*.
• Remove type=semver outputs from docker/metadata-action@v5 so the only image tags emitted are type=ref,event=tag and type=raw,value=latest.

Testing

• Ran a Python assertion script that checked the workflow contains - 'v*.*', no longer contains v*.*.*/*.*.*, and that image tags are limited to type=ref,event=tag and type=raw,value=latest, and it succeeded.
• Attempted YAML parsing with PyYAML in Python which failed due to the environment lacking the yaml module.
• Parsed the workflow YAML with Ruby using YAML.load_file which succeeded.
• Ran git diff --check which succeeded.
