test-storybook --coverage cmd fails with pnpm

[qwerdee]

Describe the bug

Coverage report fails when using pnpm as package manager. test-storybook command runs npx nyc .. internally which does not work

Steps to reproduce the behavior

1. Set up storybook with addon test-runner and addon-coverage
2. install dependencies via pnpm
3. run test-storybook with coverage pnpm test-storybook --coverage

Expected behavior

Should not fail and nvm should be executed with pnpx ... instead of npx ... in a a pnpm project

Screenshots and/or logs

$ pnpm test-storybook -c libs/ui/.storybook --url=http://localhost:4400 --coverage
