Since JuliaLang/julia#57133, we see a lot of these issues in our CI at https://github.com/oscar-system/GAP.jl, when running doctests with julia nightly.

I managed to break it down to a very small mwe:

julia> using Documenter

julia> module Foo
       end
Main.Foo

julia> DocMeta.setdocmeta!(Foo, :DocTestSetup, :(using Foo); recursive=true)
WARNING: Detected access to binding `Foo.##docmeta#274` in a world prior to its definition world.
  Julia 1.12 has introduced more strict world age semantics for global bindings.
  !!! This code may malfunction under Revise.
  !!! This code will error in future versions of Julia.
Hint: Add an appropriate `invokelatest` around the access to this binding.

Yes, the documenter code needs to be fixed. Usually if have done that first, but were trying to get the first rc out, so I'm focusing on the Julia base changes first.

@Keno well @lgoettgens also submitted a potential fix as PR #2622 so I hope that can be merged and released quickly
