Bug Fix: Flask and Celery Docker Images

Modified: requirements_2.7.txt

Change: Downgrade `gevent` to `1.2.2`

I was having issues running the Flask and Celery containers. The issue was due to installing `gevent` version `1.4.0` which is not supported by Python 2 as it can be seen in the table at: https://pypi.org/project/gevent/#description

After using the supported `gevent` version the issue was solved.

I'm running the project on ubuntu server v22.04
