Recently I was wandering if there is someone or some group preserving , collecting , organizing and publishing all the knowledge of mankind ever created throughout its existence so that if ever mankind faces the 6th mass extinction we don't have to reinvent the wheel and can have a kick start to our new post apocalyptic civilization .
That is pretty much exactly the goal of the Wikimedia Foundation which runs Wikipedia and its sister projects.
But by now we figured out what wikis can do well and what not. Wikis are suitable for crowdsourcing objective facts about the world (all it takes is one person to add any given fact), they are not a universal remedy for everything, especially not contentious issues or useful instructional materials.
I have made more than 100000 edits to their projects. I don't participate there anymore. The time when they were a force for good in the world is long past.

Their goal isn't to collect all human knowledge, only notable human knowledge.
See https://en.wikipedia.org/wiki/Wikipedia:Notability and https://en.wikipedia.org/wiki/Wikipedia:What_Wikipedia_is_not#Wikipedia_is_not_an_indiscriminate_collection_of_information .
I don't personally know of any but in a similar vein there are some stone monuments intended to convey information after an apocalypse like the Georgia Guidestones or the nuclear waste site warning stones. GitHub put a snapshot of all active code repositories from 2020 in arctic permafrost, and there is the arctic seed vault for preserving plant species.
Man those nuclear waste messages makes it sound like it's a cursed land
"On July 6, 2022, an explosive device was detonated at the site, destroying the Swahili/Hindi language slab and causing significant damage to the capstone. Nearby residents reportedly heard and felt explosions at around 4:00 a.m" the rocks got destroyed by a mere explosive and they thought it could survive a nuclear war lol
Check out this book: https://en.m.wikipedia.org/wiki/The_Knowledge:_How_to_Rebuild_Our_World_from_Scratch. It analyses that precise question in the first chapter. The author argues that even though Wikipedia is probably the closest thing there is, there is a clear lack of practical knowledge that will be essential in the situation that you are describing. Science progress heavily relies on industrial progress, and even if you know how to build something that doesn't mean that you can do it, as there are other things that are required first.
I'm surprised no one mentioned projects like libgen and scihub. They are much better than Wikipedia imo.
imo zlib is much better but they keep changing their domain ... also sci hub is only for research papers which most people can understand
