ci(pm-bundle): skip the linux legs until the larger runners run 24.04

The ubuntu-latest-32-* larger runners boot ubuntu-22.04 (glibc 2.35), and
the prebuilt llama-server in the native payload needs GLIBC_2.38, so the
staged-entry verification fails. Restore the two entries once the runner
images are updated.
