Merge branch 'jc/fix-2.45.1-and-friends-for-2.39' into fixes/2.45.1/2.40

Revert overly aggressive "layered defence" that went into 2.45.1
and friends, which broke "git-lfs", "git-annex", and other use
cases, so that we can rebuild necessary counterparts in the open.

* jc/fix-2.45.1-and-friends-for-2.39:
  Revert "fsck: warn about symlink pointing inside a gitdir"
  Revert "Add a helper function to compare file contents"
  clone: drop the protections where hooks aren't run
  tests: verify that `clone -c core.hooksPath=/dev/null` works again
  Revert "core.hooksPath: add some protection while cloning"
  init: use the correct path of the templates directory again
  hook: plug a new memory leak
  ci: stop installing "gcc-13" for osx-gcc
  ci: avoid bare "gcc" for osx-gcc job
  ci: drop mention of BREW_INSTALL_PACKAGES variable
  send-email: avoid creating more than one Term::ReadLine object
