Fix Typo in Local Setup Command in README.md

[xSkkarf]

Description:

There is a typo in the name of the Gunicorn configuration file. It is currently named gunicorn.config.py, but the documentation refers to it as gunicorn_config.py in the README.md file which may cause confusion or errors for users trying to set up the project locally.

Current (Incorrect) Command:

cp ihr/config/gunicorn_config.py ./

CorrectCommand:

cp ihr/config/gunicorn.config.py ./

Notes:

happy to open a PR to fix it.
