Memory Leak with Fetch

Description

I have encountered a memory leak issue when using the fetch function in my React Native application. The memory usage gradually increases over time in iOS, leading to performance degradation and potential crashes.

React Native Version

0.72.4

Steps to reproduce

1.	Create a React Native project with the necessary dependencies.
2.	Implement a screen or component that utilizes the fetch function to make API requests.
3.	Monitor the memory usage of the application over an extended period.
4.	Observe that the memory usage consistently increases during and after making multiple fetch requests.

minimal example:
https://github.com/clemensmol/rn-fetch-memoryleak

Beginne damit, das minimale Beispiel unter https://github.com/clemensmol/rn-fetch-memoryleak mit React Native 0.72.4 auf iOS auszuführen und den Speicher während wiederholter fetch requests zu überwachen. Verfolge das Anfrageverhalten und vergleiche den Speicher vor und nach der Ausführung des Reproducers; als erledigt gilt die Aufgabe, wenn das demonstrierte Speicherwachstum behoben ist und die Reproduktion kein Leck mehr zeigt.
