ci/cd: lint Python scripts using pylint

This commit integrates `pylint` into the CI/CD pipeline to improve the
quality of Python scripts within the project. By enforcing stricter
linting standards, the aim is to identify and correct potential issues
more efficiently, ultimately contributing to more reliable and
maintainable code.

Changes:

- Introduce `npm run lint:pylint` command to facilitate unified way to
  run linting on different environments.
- Include `npm run lint:pylint` in the CI/CD workflow to ensure all
  commits adhere to established Python coding standards.
- Fix an issue identified by `pylint` in `configure_vscode.py`.
- Rename the workflow to match the latest naming convention.
