"Collection was modified" exception is thrown when renaming a group in the Addressables Groups window while using Perforce

Basic reproduction steps:

1. Set up a Unity project with the "Addressables" package installed
2. Create a new Addressables Group
3. Set up a Perforce workspace
4. Connect unity to perforce in Edit > Project Settings > Version Control
5. Submit the project to Perforce so the group files become read-only on your disk
6. Select the group in the "Addressables" window (so its properties are actively displayed in the Inspector window)
7. Rename the group in the "Addressables" window
8. Observe the Console

Actual result: "Collection was modified" exception is thrown
Expected result: no exception is thrown

Reproducible with: 2.10.1 (6000.3.10f1)

Reproducible environment: Windows 11
Not reproducible environment: No other environments tested

Workaround: The customer successfully bypassed the exception by appending “.ToList()” to create a copy of the collection before iterating: “foreach (var schema in m_Schemas.ToList())”

Note: Not reproduced by CQA (Wasn't able to reproduce the issue from scratch with the customer’s packages and editor version)
