Edit docs CI workflows to accommodate Docusaurus

- Copy the `gravitational/teleport` source into the `content` directory
  of a `gravitational/docs-website` clone and overwrite the `git-update`
  yarn script with a no-op command. With way, we can use the
  `gravitational/teleport` clone across multiple workflow steps (e.g.,
  the prose linting step), and can identify a branch to pull using the
  `actions/checkout` defaults. Name the submodule directory `current` to
  match the expectations of the Docusaurus site.

- Remove the Vercel preview workflow. After the docs engine migration,
  we'll no longer need to deploy a preview to Vercel in order to show
  docs authors what their potential changes look like on a rendered docs
  site.

Also fixes spelling errors caught by a later version of cspell.
