Feat/ghaar/capstone init

[SkeloGH]

Background

Trying to get started with the project led to stumbling with a few bumps that can be avoided to newcomers. (e.g. finding that dotenv package actual name is python-dotenv)

Problem

• Capstone project scaffold doesn't indicate recommended python version unless reading the provided scripts.
• Requirements file is non-existent, thus finding the right package names to any dependencies could take valuable time.

Repro steps

• Clone the repo bare-bones
• Try to install dependencies to run capstone_project/main.py
• Result: modules can't be found

Solution proposal

• Define a python version in a file
• Create requirements file
• Add instructions to the README file

Testing steps

• Clone the repository again in a new directory to simulate a fresh start.
• Check if the Python version file (.python-version) exists and specifies the correct Python version.
• Run pip install -r requirements.txt to install the dependencies from the newly created requirements file.
• Check if the python-dotenv package is correctly listed in the requirements file.
• Try running capstone_project/main.py again. The modules should now be found and the script should run without any errors.
• Check the README file for the new instructions on setting up the project. Follow these instructions in a new environment to ensure they are clear and correct.
