fix: quickstart.Dockerfile after updating Dockerfile

[gabrielmbmb]

Description

This PR updates the quickstart.Dockerfile so it's compatible with the updates done for the Dockerfile in #3221.

Also, the Dockerfile has been updated to create the virtualenv in a common path between the builder stage and the final stage, otherwise, Python binaries will throw this error:

bash: /home/worker/my-virtual-env/bin/uvicorn: cannot execute: required file not found
