Fabric e2etests for large snapshots are broken

Problem Description

Currently affecting main and 0.75

Broken Tests
FlatList - Basic
ScrollView - refresh Control
SectionList - Scrollable

While working on the 0.75 branch these tests broke due to an Invalid string length error. I'm thinking it's because these are the only tests with 1000+ items and the toJson() function must have put a cap on what it can process but further investigation is needed. Check pages out locally and they render/work as intended

Steps To Reproduce

1. Run tests on 0.75 branch
2. Look at Pipeline (https://dev.azure.com/ms/react-native-windows/_build/results?buildId=592440&view=logs&j=20253376-38f7-5084-b900-818d1e6181d3&t=e4bc6543-c5eb-5bc9-6033-5ab4b4216285)

Run the listed Fabric e2e tests on the 0.75 branch and inspect the linked pipeline logs for the Invalid string length failure. Compare the FlatList - Basic, ScrollView - refresh Control, and SectionList - Scrollable cases, then investigate whether toJson() is involved; done means these tests pass while the pages continue to render and work as intended.
