Support nested directories in the lip directory

[JoelMarcey]

Right now, we cannot have nested directories in the lip directory.

8:54:41 AM: > node scripts/createDocsDir.js && docusaurus build
8:54:43 AM: Creating an optimized production build...
8:54:43 AM: Error: EISDIR: illegal operation on a directory, read
8:54:43 AM: npm

8:54:43 AM: npm ERR! lips@0.0.0 build: `node scripts/createDocsDir.js && docusaurus build`
8:54:43 AM: npm ERR! Exit status 1

See commits of #7 for an example.

@JoelMarcey any status update here?

Now that dip.diem.com has moved to Docusaurus v2, nested directories //should// work, I believe. In fact, we are almost done with a feature that automatically generates the sidebar based upon the docs directory structure - facebook/docusaurus#3464.

The one thing we would need to check is whether because we are naming the directory lip instead of docs, whether that will still cause an issue.

@jjwill Are you / Dfuzr still managing this site? Or is that on the Diem team now?
