fix: update libnvidia-container to 1.19.0, add version sync guard

libnvidia-container 1.18.2 doesn't know about libnvidia-tileiras.so
(new in driver 595), causing CUDA to fail in Docker containers with
"driverInitFileInfo result=11". Version 1.19.0 adds this library.

Also adds a sync guard to update-versions.yml to ensure
libnvidia-container always matches the toolkit version, preventing
future mismatches from independent release schedules.
