Unable to execute commitizen from within nested directory inside the repository

In my setup, the git repository is placed in `/home/user/Code/namespace/prj-name/`, but all the CI/CD code is placed in `/home/user/Code/namespace/prj-name/cx` (in part, because it is not a JS project, and I want to "simplify" the directories/files structure at the root of the project).

Before that, I had everything in the project root, and it was running fine, but I'm in the middle of a refactoring process for the build system, hence the change.

Husky seems to adapt pretty well to this setup (I even checked the generated shell scripts inside `.git/hooks`, and it takes care of changing directory before running the hooks).

But... `commitizen` fails to do the same, and it insists on trying to load the modules from the "root" of the project, even if I set the `$NODE_PATH` environment variable to point the `/home/user/Code/namespace/prj-name/cx` directory (where `$PWD` points too, due to how Husky works).

Here you can see the error message, sadly it does not show the involved line numbers, and I couldn't follow the "jump" from `dist/commitizen.js` to `dist/commitizen/adapter.js`:
```
> @namespace/prj-name@0.0.1 git-cz /home/user/Code/namespace/prj-name/cx
> git-cz "--hook"

Could not resolve /home/user/Code/namespace/prj-name/node_modules/cz-conventional-changelog. Cannot find module '/home/user/Code/namespace/prj-name/node_modules/cz-conventional-changelog'
Require stack:
- /home/user/Code/namespace/prj-name/cx/node_modules/commitizen/dist/commitizen/adapter.js
- /home/user/Code/namespace/prj-name/cx/node_modules/commitizen/dist/commitizen.js
- /home/user/Code/namespace/prj-name/cx/node_modules/commitizen/dist/cli/git-cz.js
- /home/user/Code/namespace/prj-name/cx/node_modules/commitizen/bin/git-cz.js
- /home/user/Code/namespace/prj-name/cx/node_modules/commitizen/bin/git-cz
```

Here a simplified version of my `package.json` file (also in the `cx` directory):
```json
{
"name": "@namespace/prj-name",
"version": "0.0.1",
"description": "Project Name",
"scripts": {
"commitlint": "commitlint",
"git-cz": "git-cz"
},

"husky": "^4.2.5"
},
"commitlint": {

],
"rules": {

"subject-min-length": [2, "always", 3],
"subject-max-length": [2, "always", 50],
"body-max-line-length": [2, "always", 80]
}
},
"config": {
"commitizen": {
"path": "./node_modules/cz-conventional-changelog"
}
},
"husky": {
"hooks": {
"prepare-commit-msg": "exec < /dev/tty && npm run git-cz -- --hook || true",
"commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
}
}
}
```

Is there any configuration option (or environment variable) I can use to tell commitizen how to behave?

Thanks for your attention.
