Change Description

This MR updates the README to account for the Ubuntu 24.04 changes described in #41153 (closed). I specified the Ubuntu version because AFAIK the apparmor_restrict_unprivileged_userns kernel setting did not exist before 23.10 (but the feature was only made default starting from 24.04), so trying to set it on older systems may fail.

How Tested

Builds on Ubuntu 24.04 were reported to succeed using these instructions. I myself could verify that the unprivileged user namespace restrictions are disabled as expected using the new instructions.
