Description of Changes

This pull request moves Python dependencies from pip.yml to a requirements.txt file for easier management. Here’s what was done:

1. Created a requirements.txt file:

   • Added all dependencies, such as Flask, Werkzeug, and uwsgi, into this file to keep things organized.

2. Updated pip.yml:

   • Adjusted the Ansible tasks to install dependencies from requirements.txt instead of listing them directly in the file.
   • Added steps to:
     • Update pip and related tools like setuptools and wheel.
     • Install dependencies in a virtual environment using the requirements.txt file.

3. Dependabot Integration:

   • Made sure tools like Dependabot can track and update dependencies in requirements.txt automatically.

4. Tested the Changes:

   • Ran the updated playbook to confirm everything works as expected.

These changes make it easier to manage and update dependencies while keeping the setup clean and consistent.

See my comment below, please also take a look at the message returned by the QA checks failure regarding the lack of capital letter after the square bracket, eg:

[prefix] done something should be [prefix] Done something.

I wouldn't move these because we're always upgrade to the latest version available.

The aim is to move only the python packages that we are pinning to as pecific version range, so that dependabot can help us update those more with less intervention from our end.
