Backport #31931 by @lunny
All refs under
refs/pullshould only be changed from Gitea inside but not by pushing from outside of Gitea.This PR will prevent the pull refs update but allow other refs to be updated on the same pushing with
--mirroroperations.The main changes are to add checks on
updatehook but notpre-receivebecauseupdatewill be invoked by every ref butpre-receivewill revert all changes once one ref update fails.
