fix(vars-check): include generator scripts in test closure

The vars-check test was failing because it only included the
runtimeInputs of generators but not the actual generator scripts
themselves. This caused the test to fail when trying to execute
generators that reference local files (like generate.py).

Added allGeneratorScripts to the closureInfo to ensure all generator
scripts and their dependencies are available in the test environment.
