…sponseHeader}Start

FF152 supports PerformanceResourceTiming.finalResponseHeadersStart and PerformanceResourceTiming.firstInterimResponseStart in https://bugzilla.mozilla.org/show_bug.cgi?id=2006340

This adds a release note, along with a tiny update to cross link a few status codes from those docs.

LGTM, apart from one nit.

### APIs

- The {{domxref("PerformanceResourceTiming.firstInterimResponseStart","firstInterimResponseStart")}} and {{domxref("PerformanceResourceTiming.finalResponseHeadersStart","finalResponseHeadersStart")}} properties of the {{domxref("PerformanceResourceTiming")}} interface are supported.
These can be used to measure how long it takes to the browser to receive interim HTTP responses and the final HTTP response after sending a request, respectively.
