Fix stale pandoc-oracle test fixtures after 3.10 ceiling bump

d747904 bumped PANDOC_ORACLE_MAX_VERSION to (3, 10) but left two test
fixtures pointing at the old ceiling: PANDOC_ORACLE_RANGE_CASES still
expected (3, 10) to be out of range, and the gate-failure message test
still asserted on "3.9". Rewrite both to derive boundary values from
PANDOC_ORACLE_MIN/MAX_VERSION instead of hardcoded literals, so future
ceiling bumps propagate automatically.
