Remove Docker build step; add Azure Web Apps deploy

This commit removes the Docker build and push steps from the `cicd.yml` file.
In their place, a new deployment step has been added using the `azure/webapps-deploy@v3` action,
which specifies the application name and the image tagged with the current GitHub SHA.
