ci: Install pytest via apt(8)

With Ubuntu 24.04 installing it via pip gave this error

  error: externally-managed-environment

  × This environment is externally managed
  ╰─> To install Python packages system-wide, try apt install
      python3-xyz, where xyz is the package you are trying to
      install.

      If you wish to install a non-Debian-packaged Python package,
      create a virtual environment using python3 -m venv path/to/venv.
      Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
      sure you have python3-full installed.

      If you wish to install a non-Debian packaged Python application,
      it may be easiest to use pipx install xyz, which will manage a
      virtual environment for you. Make sure you have pipx installed.

      See /usr/share/doc/python3.12/README.venv for more information.

Installing it via the package manager is the better option anyway...

Under Ubuntu 22.04 it only installs a /usr/bin/pytest-3 binary, rather
than installing a /usr/bin/pytest binary and symlink for pytest-3, so
use pytest-3 as the command.
