Setting Git commit SHA as an environment variable using Azure's webapps-deploy GitHub Action

Question

I'd like to set the current GitHub commit SHA as an environment variable when deploying my application using webapps-deploy: https://github.com/Azure/webapps-deploy

How can I achieve this?

My current yaml looks something like this:

# Docs for the Azure Web Apps Deploy action: https://github.com/Azure/webapps-deploy
# More GitHub Actions for Azure: https://github.com/Azure/actions
# More info on Python, GitHub Actions, and Azure App Service: https://aka.ms/python-webapps-actions
