chore: update docker workflow to include tags

- Add support for tagging workflow triggers on pushes
- Include version tags following the pattern 'v*'

This change enhances the Docker workflow by allowing the CI/CD
pipeline to respond to version tags, which is beneficial for
versioned releases and better management of deployment processes.
