Extra Documentation for Anchors

[GiantRobots]

We have this documentation which is excellent around rel=noreferrer and noopener

I think we should enhance this with a few links to other references like to this MDN page for referrer policy https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referrer-Policy . I think it may be worthwhile telling people for extra security adding headers or meta tags with the appropriate settings can set the referrer for all links ex.

<meta name="referrer" content="noreferrer noopener">

Hi @GiantRobots

Would you consider adding this as a PR submission? Seems like a great idea to include references to me.

Hi @GiantRobots! Would you still be interested in submitting this as a PR?
