macOS build fails at CMake configure: find_package(fizz) not found after advancing Velox

[natashasehgal]

Issue:
After #1466, the Axiom Linux and macOS builds began failing.

Advancing the Velox submodule to 457bb8ffd7674d4b2396fc8486451f1acc7ccd2b (from 8c14870cef7ffeed62e3a1b6fdc43b5e69790dd1) fixes the Linux build, but the macOS build then fails at CMake configure time because the fizz package is not found: #1467

Failed Jobs:
Release: https://github.com/facebookincubator/axiom/actions/runs/27293371911/job/80619576441?pr=1467
Debug: https://github.com/facebookincubator/axiom/actions/runs/27293371911/job/80619576403?pr=1467
