Hello @Nathan Sundararajan
| WARNING: You are using pip version 20.2.3; however, version 22.3 is available.
isn't an error and would not prevent your site from being deployed and running.
You won't be able to upgrade the pip of your webapp because you will not have access to system files.
Instead you can upgrade pip of your virtualenv, which you can do by adding a line in deploy.cmd file before install requirements.txt command.
env\scripts\python -m pip install --upgrade pip
Remember not to upgrade pip with pip (env/scripts/pip) else it will uninstall global pip.
