Add GitHub workflows for JavaScript and Python autofix (#2381)

This pull request adds GitHub workflows for JavaScript and Python
autofix. The JavaScript workflow is triggered on pull requests and
pushes to the main branch for changes in the "src/frontend" directory.
It sets up Node.js, caches Node.js dependencies, installs Node.js
dependencies, and runs Prettier for code formatting. The Python workflow
is also triggered on pull requests and pushes to the main branch for
changes in the "poetry.lock", "pyproject.toml", "src/backend", and
"tests" directories. It installs Ruff and runs Mypy for type checking
and code formatting.
