Documentation Error

If you have installed the dependencies in the root of the Medusa repository (i.e., if you have a node_modules directory at the root of the Medusa repository), this will cause an error when running the documentation website.

This is because the content resides in docs/content. When that content is being imported from there, a mix up can happen between the dependencies in the root of the Medusa repository and the dependencies in www/docs which causes an invalid hook call error.

For that reason, when the start and build scripts in www/docs are used, the clean-node-modules script is called. This script deleted the node_modules directory in the root of the Medusa repository.
