Required debug information missing message should be actionable

### Problem Statement

The following warning of issues confuses users cause it doesn't explain how to solve the problem. We have one complaint here https://github.com/getsentry/sentry-cocoa/issues/2801.

### Solution Brainstorm

It would be great if the warning above would explain that the user might need to upload dSYMs with a link to the relevant platform docs.

For this [issue](https://sentry-sdks.sentry.io/issues/4058463753/events/d60d67f7617340b29393caffbb19cf9a/) a link to the [Apple dSYMs docs](https://docs.sentry.io/platforms/apple/dsym/) would help.
