[SYCL][Devops] Revert requiring password for sudo

Apparently, I overlooked part of the documentation saying that docker
secrets are only available for containers running as a service which
isn't the case for our build/test CI pipeline.

Therefore, I'm partially reverting #16411 so that our containers once
again use `sycl` user which has password-less `sudo` access.

This PR also reverts #16436 to re-enable GPU reset.

 ## Changing Docker user

-Note: it **does not** have password-less `root` access.
+By default all processes within our containers are run as the `sycl` user which
+has password-less `sudo` access.
 
 If you want to change the user, you can do that by specifying the
 `-u <username or uid>` option when running the container.
 
-All containers come with the `/user-setup.sh` script which can used to create
-the `sycl` user which has all the same groups as the `sycl_ci` user, but also
-has password-less access to `root`. Use the script as follows:
-
-```bash
-# Note: the script requires root permissions to create a new user
-/user-setup.sh --regular
-# Switch to the newly created user
-su - sycl
