Fabric e2etests for large snapshots are broken

[TatianaKapos]

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)

This issue is also present on the 6/18 integration, and I have commented the tests out pending a fix for this error. Verified the affected pages in the Tester App render as expected. However, on the SectionList example, when clicking on the 'scroll to' button to go to the listed section, all the buttons directed me to the top, rather than a specific individual section. @TatianaKapos did you see this on your preview branch as well?

@Yajur-Grover let me double check! Are you seeing this on Paper/Fabric? We may need to see if it's coming from the integration or if it's been broken on main.

Was seeing it on RNTesterApp-Fabric. Will check the app on main as well.
