Removed an undocumented, broken behavior where README.md files would be copied to index.md if it did not exist, leading to broken links in the TechDocs UI.

WARNING: If you notice 404s in TechDocs after updating, check to make sure that all markdown files referenced in your mkdocs.ymls' nav sections exist. The following flag may be passed to the generate command to temporarily revert to the broken behavior.
