Remove image build from CI pipeline (#108)

* chore: move Docker image build to release workflow and bump version

- Remove Docker image build steps from CI job
- Move Docker image build to deploy job (releases only)
- Images are now built and pushed only on release tags
- Bump version from 1.5.0 to 1.5.1

* chore: add latest tag to Docker release images

- Images on release will now be tagged with both version tags and latest
- Ensures users can always pull the latest stable version

* chore: sync version to 1.5.1
