Unresolved module when cz-customizable is located under git base directory

[GradedJestRisk]

In this sandbox, nested 2 levels under repository root, npx git-cz triggers this message

$ pwd
<BASE_DIR>/git-training/config/cz_customizable/sandbox
$ npx git-cz
Could not resolve <BASE_DIR>/git-training/node_modules/cz-customizable. 

However, when moved to the repository's root, everything is fine. The fix is easy, copied from commitizen README
