GSM library SMS.write() reference page correction request

The page intended to show how to use the `SMS.write()` function doesn't.
Ref: https://www.arduino.cc/en/Reference/GSMSMSWrite

There is an example given but it doesn't show or use '.write'
or explain how it is different than '.print'. Could anyone update the example?

Start with the GSMSMSWrite reference page linked in the issue and inspect its current example and description of SMS.write(). Compare the example with the requested write-versus-print distinction; done means the example demonstrates SMS.write() and the page explains how it differs from SMS.print().
