Improve dependencies management

[Martolivna]

This PR enhances dependencies management with the following updates:

• Transition to using pip --constraints for constraints handling, replacing the use of pip-compile --constraints.
• Separate development and base requirements; base requirements are no longer included in the development requirements.
• Update the README for the requirements installation section.
• Update CI job's requirements installation.

These changes aim to improve clarity and reduce redundancy in the project's dependency management.
