fix(jenkins): move audit to docker-ubuntu24-xlarge for glibc 2.39 (SAST exit 51) (#3519)

The analyzer-manager SAST sub-binary (zd_scanner) is a PyInstaller-
packed Python 3.14 app with a native extension built against
GLIBC_2.34. The docker-ubuntu20-xlarge agent ships glibc 2.31, which
is too old:

  ImportError: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34'
  not found (required by .../zd_scanner/native/_dfa.cpython-314-...so)

Switching the agent label to docker-ubuntu24-xlarge (glibc 2.39)
restores SAST and resolves the `Sast scan exit status 51` failure
seen in the Audit stage.
