[PATCH] docs: hooks: Document when shutoff-reason argument was introduced

From: Michal Privoznik <mprivozn@redhat.com> Introduced in v10.5.0-rc1~52, qemu and lxc hook scripts are executed with additional argument: shutoff reason. But wording of our docs make it looks like it's been that way forever. Make it clear this is `recent` feature.
