fix: Address code review feedback and finalize template

This commit resolves the issues identified during the code review to finalize the Python package template.

Key fixes include:
- **Dockerfile Improvement:** The runtime stage of the `Dockerfile` now adds the non-root user's local bin directory to the `PATH` environment variable. This ensures that any command-line scripts installed by dependencies are directly accessible, preventing potential runtime errors.
- **CI Optimization:** The redundant `lint-docker` job has been removed from the `ci.yml` workflow. Dockerfile linting is already handled comprehensively by the `hadolint` hook within the main `lint` job's `pre-commit` execution, making the separate job unnecessary and streamlining the CI process.
