Custom docker daemon args is not working

[shaoye]

Bug description

Got Permission denied error following the steps in #8435

1. Add environment variable DOCKER_DAEMON_ARGS to your user settings. The content should look like this:
{ "remap-user": "1000" } (Means container id 1000 will be mapped to gitpod user).
2. Start workspace
3. mkdir /workspace/tmp/me
4. Run docker image which supports running as unprivileged user e.g. sudo docker run -it -u node -v /workspace/tmp/me:/tmp node sh
5. Create file within container e.g. touch /tmp/foo
6. Verify that the created file has gitpod:gitpod permissions in the workspace

got permission denied at step 5,

touch: cannot touch '/tmp/foo': Permission denied

the node user can't create any files since /tmp is owned by gitpod user

/tmp$ ls -al

Hi, @shaoye. I investigated this issue and found the name of the env was wrong.
You set DOCKER_DAEMON_ARGS, but DOCKERD_ARGS is the right name.
https://www.gitpod.io/docs/environment-variables#user-specific-environment-variables

However, the name of the environment variable in the PR summary was incorrect. I have corrected that as well. Thanks.

Can confirm this works - super useful!
