update-hook: remove e-mail sending hook.
The update hook's only job is to decide is a particular update is allowed or not. It was not the right place to send out update notification e-mails from to begin with, as the final stage of updating refs can fail after this hook runs.

# hooks.announcelist
|

# This is the list that all pushes of annotated tags will go to. Leave it
