[Github] Fix LLVM Project Tests Workflow on Linux

[boomanaiden154]

This patch fixes the LLVM project tests workflow on Linux. Two changes were needed. Firstly, some commands need to be performed with sudo now that the container executes as a non-root user. Second, we needed to change from ubuntu-latest to ubuntu-22.04 as ubuntu-latest not defaults to ubuntu-24.04 which causes setup-python to install a python executable linked against a newer version of glibc that is not found on ubuntu 22.04, which causes failures when CMake cannot execute the python interpreter that it finds.
