Fixes dotnet#24077 Beginning in C# 10.0, records may declare a `ToString` method as `sealed`. This prevents derived records from creating an override. Effectively, that means the `ToString` output will not include the runtime type information. (All members and values are displayed, because derived records will still have a PrintMembers method generated.)
