ci(build): shadow /__e/node24 with glibc-2.17 Node 20 in manylinux2014

GitHub's runner now forces actions/checkout onto Node 24, which needs
glibc >= 2.28; the manylinux2014_x86_64 container is glibc 2.17, so the
stock /__e/node24 binary aborts with GLIBC_2.27/2.28 not found and the
checkout step fails. There is no glibc-2.17 build of Node 24, so reuse
the glibc-2.17 Node 20 binary for the node24 path too -- bind-mount
/node20217 over /__e/node24 as well. checkout's JS runs fine on it.
