Fixes#7260
[Internal Review Topic](https://review.docs.microsoft.com/en-us/aspnet/core/fundamentals/url-rewriting?view=aspnetcore-1.0&branch=pr-en-us-9575)
* Big UE pass ... this one has only been lightly updated since it was written. API links ... latest styles applied ... 🌷 table beautification 🌹 ... *the works!*
* Enhancement via feedback from @raberana ... and we did it with nine years to spare! 🎉😄
* Takes the samp to 2.2. I'll note it on the sample update tracking issue.
* Linking to 1.1 PDF. Note that without the metadata moniker range, there's no indication that the topic's content is 2.1+ on a <2.1 version load.
