Add Matching Sibling Frames to Fingerprint Rules

### Problem Statement

I would like to have the same matching sibling frames capability in stack trace rules listed here https://docs.sentry.io/concepts/data-management/event-grouping/stack-trace-rules/#matching-sibling-frames but for fingerprint rules.

### Solution Brainstorm

_No response_

### Product Area

Processing

Start with the linked Sentry documentation section on matching sibling frames and trace how the processing area handles stack-trace and fingerprint rules. Define the expected fingerprint-rule behavior and its edge cases before locating the relevant implementation and tests; done means the capability is supported with coverage for the intended matching behavior.
