The answer is quite simple: the server only accepts HTTP/1.x.
That's quite normal considering that HTTP/2 introduces quite a few
additional attack vectors, while the nginx.org site contains only
a few resources per page, so HTTP/2 have no benefits for the site.
(Further, since the site doesn't use SSL by default and rather
have it available for those who want to use SSL for some reason,
using HTTP/2 is essentially not possible by default.)
