Formatting: Loosen the type checking in _sanitize_text_fields().

Browse Source 
[44618] added strict type checking to `_sanitize_text_fields()`, which has caused some compat issues with plugins.

We can loosen the type checking to only reject objects and arrays, and cast other types to string.

Props Nick_theGeek, pento.
Fixes #41450.
