CI: Fix container image build workflow

Ubuntu Noble runners now need the `--break-system-packages` option to
install system-wide Python packages. However this option is absent from
pip on our Ubuntu Jammy arm64 runners.

Detect the distribution version and run the appropriate command.

note: Removed requests pinning as it was unpinned before.
