The wiki has documented "21. Set notification for customscript" since 2022 but the implementation (#4193) was never merged, so following the wiki failed with "Cannot find the hook file". Same interface as documented: the script gets subject, content and status code as three arguments. Unlike #4193, the target script is invoked directly instead of through eval -- the subject/content contain domain names and CA messages, and eval would allow command injection through them. https://github.com/acmesh-official/acme.sh/issues/6377
