Incompatibility with ubuntu 24.04

[mraron]

Ubuntu 24.04 is now more restrictive about user namespaces (similar issue with workaround: lima-vm/lima#2319).

$ task-maker-rust 
Error: Failed to start local worker

Same issue here.

It seems that running the command with sudo fixes the issue, but I would rather run this without root privileges.

Seems like an Ubuntu issue to me, the issue linked above says that this should fix it:

    echo "kernel.apparmor_restrict_unprivileged_userns = 0" >/etc/sysctl.d/99-userns.conf
    sysctl --system

This is a system configuration issue, so we probably should not do more than document the workaround.
