remove router-bridge (#603)

Now that the router has updated its MSRV to a version which is not
supported by deno, keeping `router-bridge` around breaks the release
process for `apollo-composition`. This commit removes it entirely while
also bumping the version of rust used by circleci to the latest stable
version.
