With the current docs directory setup, I'm making too many mistakes and have to manually address path changes and directory moves on deploy. This makes for a frustrating experience developing locally and shipping releases. With this PR, we're basically back to the same setup from v3—duplicating the dist directory into our docs directory. Not the most ideal, but very straightforward for me as the release manager.
* update docs path from docs/4.0/ to docs/4.1/
* bump version to 4.1.0
* Update redirects to work for 4.1 docs move
* Update docs version switcher to include latest and link to 4.0 docs
* re-run dist
* Update package-lock.json
* Update docs-navbar.html
