post_forum: fix for good
includes CI test commit for me, will remove later
- Before, we required the
<!--more-->
tag - which isn't always used, so I added a check for that. - However, the CI will still fail because without a tag, the post writer hasn't ensure that only a selected portion is posted to discourse. For example, in our workshop posts, we might embed image or figures, this will not work. So best to just always add a more tag.
- However, the post will still be posted, since this can be updated manually in the forum if something goes wrong quite easily. The CI failure is there to inform the user
- I also improved the logging a bit
- Fixed the CI typo
