Misleading method parameter comment for $reply

Updated the method attribute signature comment with a more accurate description. Please review my MR.

In Drupal core changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → . Also mentioned on the version → section of the list of issue fields documentation. Thanks.

Applied the suggestion. Thanks.

Seems straight forward.

@peter majmesku fyi you shouldn't RTBC your own stuff.

Well, I RTBC'd your change.

I cannot add multiple email addresses in reply-to. It says invalid

@java008 We don't generally handle support requests in the Drupal.org core issue queue, so you will want to look elsewhere (like the Drupal community Slack) to get support for your issue. Thanks!

Thanks for working on this. I recommend some additional documentation on the format of the paramenter. We don't need to repeat the full $to docs, but we should at least say it has the same format as that parameter. Thanks!
