Get RUN_AS_DEVIN working with app sandbox

[xingyaoww]

The reason why RUN_AS_DEVIN was not working properly is that SANDBOX_USER_ID is not properly setted up. os.getpid() from the app container will return UID=0, which creates the issue of https://github.com/OpenDevin/OpenDevin/issues/936.

This PR fix:

• Allowing RUN_AS_DEVIN with app container. The caveat is that the user need to pass-in their UID when starting the app container. I have updated the readme accordingly

docker run \
    -e LLM_API_KEY \
    -e WORKSPACE_MOUNT_PATH=$WORKSPACE_BASE \
    -v $WORKSPACE_BASE:/opt/workspace_base \
    -e SANDBOX_USER_ID=$(id -u) \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -p 4000:3000 \
    --add-host host.docker.internal=host-gateway \
    ghcr.io/opendevin/opendevin:latest

• Make SANDBOX_USER_ID consistent: the app will run with a user with UID of SANDBOX_USER_ID, which won't cause a permission issue in writing to workspace; the sandbox will run with a UID of SANDBOX_USER_ID as well.

Seems integration tests have captured a bug?https://github.com/OpenDevin/OpenDevin/actions/runs/8866160837/job/24343257827?pr=1426#step:6:66:

chmod: changing permissions of 'hello.sh': Operation not permitted
