Docs - Would be helpful for customers if we provide docs how to control the ANR ingestion

[Angelodaniel]

Problem Statement

Looking to have explanation about:
Finding a way to make all future ANRs are non fatal, low priority only get ANRs for customers app (not libraries).

Solution Brainstorm

Right now all ANR's are just send in, but having a way to control this with examples ideally prevents the customer from getting spammend with notifications and doesn't require them to dig through the code to figure it out.

@Angelodaniel so you're suggesting something like having a code snippet with the beforeSend hook that modifies the level of ANRs so they become low priority in Sentry and drops ANRs that don't have in-app frames?
