Motivation Behind Feature

If a dependency in the docs changes, npm will install it automatically on your machine. To avoid this, we should pin docs dependencies to specific versions.

Feature Description

Pin docs dependencies to specific versions.

Alternatives or Workarounds

1. Specify exact version numbers in package.json.
2. Specify a npm-shrinkwrap.json file.
3. Specify a package-lock.json file.
