change patching sample to use start_to_close_timeout for activities

[antmendoza]

What was changed

With schedule_to_close, if the developer restarts the worker after the activity is scheduled, the activity will throw a non-retriable error after 5 minutes.

Changed to start_to_close to make the activity failure retriable

Why?
