System.Threading.Timer.Change docs incorrect

### Describe the issue or suggestion

The [docs ](https://learn.microsoft.com/en-us/dotnet/api/system.threading.timer.change?view=net-8.0#system-threading-timer-change(system-int32-system-int32)) for each of the overloads of Timer.Change say the following:

> Exceptions
[ObjectDisposedException](https://learn.microsoft.com/en-us/dotnet/api/system.objectdisposedexception?view=net-8.0)
The [Timer](https://learn.microsoft.com/en-us/dotnet/api/system.threading.timer?view=net-8.0) has already been disposed.

But it looks like this was intentionally changed in .NET 8 to return false when the timer has been disposed instead of throwing an exception. I think the docs should be updated here, and maybe even a note on the behavioral change if that also seems appropriate.
