As of browser SDK 7.38.0, we now log the render-blocking status reported by the browser in resource spans' `data` hash. If a value is present and that value is `non-blocking`, ignore our heuristics and treat the value as non-blocking. This commit also updates each test case to start from a valid event and then minimally mutate it into an invalid one, because I was losing confidence that each test was really testing what it should.

👍 checking for non-blocking to exclude it vs. render blocking to include.

As of browser SDK 7.38.0, we now log the render-blocking status reported by the browser in resource spans'
datahash. (Background info: MDN). If a value is present and that span isnon-blocking, ignore our heuristics and treat the resource as non-blocking in the Large Render Blocking Asset detector.This PR also updates each test case to start from a valid event and then minimally mutate it into an invalid one, because I was losing confidence that each test was really testing what it should.
