docling-parse: install a CJK face for the non-embedded font tests

The manylinux image ships no fonts, so the CJK run test depends on whatever the
resolver happens to find: two interpreters drew .notdef boxes and self-skipped
while the third drew nothing and failed. Upstream's own test runner installs a
static Noto CJK face and pins it, which makes the test assert what it is for.
