Fix GHA CI after they upgraded nodejs

They upgraded to a version that requires a glibc newer than is in the
pre-2023 ASWF containers.

See AcademySoftwareFoundation/OpenImageIO#4324

The example build is failing, but it turns out the ci build step
duplicates what happens in the validate_openexr_libs.sh script anyway,
so I'm removing it from the workflow.
