PSA: better documentation on crashes and crash metrics

[Mark Pearson]

Hi fellow community members,

We recently submitted documentation on the different ways Chrome monitors stability and attempts to improve stability:

https://chromium.googlesource.com/chromium/src/+/main/docs/stability.md

Because it’s a new top-level doc on a major priority for Chromium and Chrome, I thought it would be worthwhile to share it here.  Besides, some of us get assigned bugs about crashes 😯, so this may provide some helpful background. 

Cheers,

Mark
