Fix "Complex Example" testset for Julia 1.9+

[omus]

I noticed this failure on Julia 1.9.4:

Complex Example: Error During Test at /Users/cvogt/.julia/dev/TestReports/test/reportgeneration.jl:14
  Got exception outside of a @test
  To update the reference images either run the tests interactively with 'include("test/runtests.jl")',
  or to force-update all failing reference images set the environment variable `JULIA_REFERENCETESTS_UPDATE`
  to "true" and re-run the tests via Pkg.

Also fixed the Documenter workflow which was running into this issue:

[ Info: CheckDocument: running document checks.

I just noticed locally that I forgot to commit the new test/reference/complexexample.txt file. It's unfortunate that the CI checks still passed here as this could have resulted in this PR being merged with the reference tests being in a broken state.
