Add GitHub Actions Workflows for Django Testing, Pylint, and Black

[youzarsiph]

Description

This pull request adds three GitHub Actions workflows to the Django REST Framework repository to enhance code quality and streamline the development process. The following workflows have been implemented:

1. Django CI:

   • Purpose: Automatically run Django tests on every push and pull request.
   • Configuration: Sets up Python, installing dependencies as specified in requirements.txt.

2. Pylint:

   • Purpose: Integrate static code analysis using Pylint to ensure code quality and adherence to coding standards.
   • Configuration: Installs Pylint and runs it against the specified Django app directory.

3. Black:

   • Purpose: Automatically check code formatting using Black, ensuring consistent code style across the project.
   • Configuration: Installs Black and checks the formatting of the specified Django app directory.

Benefits

• Improves code quality through automated testing and linting.
• Enforces coding standards with Black and Pylint.
• Reduces manual effort in running tests and styles checks, allowing for quicker feedback in the development process.

Thank you for considering my contribution!

The repo already has pre-commit in place, I wouldn't recommend adding a new workflow for any of these.

Also, with the current state of Python tooling, I wouldn't even recommend using these tools as theirselves. Ruff would be nice a improvement but not sure whether it counts as "churn"
