README mentions unmaintained Express middleware

[SjorsVanGelderen]

In the installation section of the README:

The oauth2-server module is framework-agnostic but there are several officially supported wrappers available for popular HTTP server frameworks such as [Express](https://npmjs.org/package/express-oauth-server) and [Koa](https://npmjs.org/package/koa-oauth-server). If you're using one of those frameworks it is strongly recommended to use the respective wrapper module instead of rolling your own.

This Express middleware link points to a repository with seemingly unmaintained code (no update since 2017). It also says "officially supported", but I don't think the Express team endorses this middleware.

Hi @SjorsVanGelderen, I think by officially supported it means more that the oauthjs module supports the middleware.

With that being said, we have forked this repo and are actviely maintaining it, along with the express middleware adapter. Look at the new org and repos if you are interested :)
