Update the setup.py file to include requirement sets

[anilkumarpanda]

Problem Description
As of now, there is no requirement.txt , inorder to make it easier for the developers to contribute to we can define sets in the setup.py file.

Desired Outcome
The setup.py file is updated to include sets.
We should also update CONTRIBUTING.md and the different github action pipelines.

Solution Outline
Sets would be: documentation, tests, development, core, and all. E.g setup
Define these sets via install_requires and extras_require.
You can then install what you need via pip install probatus[name-of-set].

Refer this issue for the detailed discussion.
