Mention at Process.WaitForExit's parameterless overload that async standard error stream handler is also awaited

Hi!

I am reading the following page:
https://learn.microsoft.com/en-us/dotnet/api/System.Diagnostics.Process.WaitForExit?view=net-8.0

And I noticed the following:
> This overload ensures that all processing has been completed, including the handling of asynchronous events for redirected standard output.

I think this is also true for the standard **error** stream, so it should be in the documentation as well.

If I'm correct, this is the source code for that:
https://github.com/dotnet/runtime/blob/v8.0.0/src/libraries/System.Diagnostics.Process/src/System/Diagnostics/Process.Windows.cs#L179

And it handles the error stream the same way as the output stream.
