[Build] npm run clean script references absolute path instead of relative for node_modules

[unlikelyzero]

Summary

npm run clean is designed to clean the dist and node_modules folder. With the current implementation, it uses a relative path for ./dist but an absolute path /node_modules . Effectively, this means that node_modules are not cleaned on personal devices.

Testing Notes

npm install;npm run clean on any branch other than master (after this change). Note that node_modules folder persists
npm install;npm run clean after switching to a branch with this change. Note that node_modules folder is cleaned
