@Jakub-Vacek I realize now that the GH Discussions URL will be useless unless it's clickable. Is that possible to do with Oclif? If not, we should replace it with a short link.

Additionally one copy update:

"Please include these information" -> "Please include the following information:"

At least in iTerm a link (or any path really) is clickable when holding Cmd. But I think it should be a shortlink anyways — it's better readable and we can keep it up to date.
