Investigate remote user "mdwuser" for Docker deployment

[ydaponte]

Change the deployment to use a remote user instead of the root user from the devcontainer to the deployment

DoD

• Use a remote user mdwuser instead of the root user in the Docker file, post-create.sh and also the deployment
• The E2E sample needs to run successfully with no permission issues

[bsherwin]

After researching, we should update the devcontainer to use the base container here:
mcr.microsoft.com/devcontainers/python:3

And specify a remote user.
