docs(nodejs_mono_repo): update broken links in README (#1577)

Makes sure file names do not contain `/workspace/google-cloud-node/`, since the post-processor runs from the root, but the link only needs the relative directory.

Since this is a shared function, we need to make the changes in the node post-processing.
