Improve CrashReporter UI for the latest crash

Summary: I have updated the UI of the crash reporter. It doesn't show the multiple crashes now. I will work on that in other diff. This diff just updates the current UI that shows the latest crash, as per the [design](https://our.intern.facebook.com/intern/px/p/pJ11/)
