Split `requirements.txt` into `requirements-lint.txt` and `requirements-test.txt`

Description

To optimize the project setup and ensure that only the necessary dependencies are included in the production environment, we need to separate the dependencies into two distinct files:

• requirements.txt: For production dependencies only.
• requirements-lint.txt: For static code analysis dependencies.
• requirements-test.txt: For testing and code coverage dependencies.
