This renames a property I should have renamed in #65224 and matches the naming convention by the equivalent property in ReadStackFrame.

Strengthens an assertion that should have been changed via #65224.

I assume the ConverterStrategy is determined by the value held by Nullable? I.e. it can be Value, Object, Collection.

Should there be a non-IAsyncEnumerable test added that can verify a larger, nullable POCO (as a value type)?

Nullable POCOs still work, however they don't flow the state. This becomes more evident in the case of IAE which simply fails serialization.
