Start by updating module_integration_test/MODULE.bazel with rules_python 2.0.3 and run `cd module_integration_test && bazel build //...` to reproduce the toolchain error. Inspect the referenced BUILD target and rules_score error locations in the build output. Done means the module integration build completes successfully with rules_python version 2+.
