[CI:DOCS] Add hook-script example to get_ci_vm.sh
# there are no guarantees it will remain in-sync with other automation-related
# scripts. Therefore it may not always function for everybody in every
# future scenario without updates/modifications/tweaks.
+#
+# When successful, you will end up connected to a GCP VM with with a clone of
+# the upstream podman repository 'master' branch, using a remote named 'origin'.
+# If you want to customize this behavior, you will want to use a "hook" script.
+# Please use this example carefully, since git setups vary by person, you
+# will probably need to make local edits.
