Major Description
We provided with XWIKI-19125 an originalMetadataAuthor whose goal is to make a distinction between an author used to check rights (here the metadata one) and an author used only to be displayed: the original author is the one to display, but the author for checking rights with might come for a script.
It's probably interesting to have the same design for other authors we have, namely the content author and the creator.
We had already two requests on the chat about the content author (see https://matrix.to/#/!ikPtGZaGWtyblizzlR:matrix.xwiki.com/$16933182411142ysBxP:matrix.xwiki.com?via=matrix.org&via=matrix.xwiki.com&via=helsinki-systems.de and https://matrix.to/#/!ikPtGZaGWtyblizzlR:matrix.xwiki.com/$1716979675446UiPJp:matrix.xwiki.com?via=matrix.org&via=matrix.xwiki.com&via=helsinki-systems.de) and I noticed a mention for having it for creator in XWIKI-11451
