Arvados

I am running on Debian 12 and have run arvados-server install -type test as of main at 7bc4217495b405c98ea4cad8178b8136383486cf. When I try to build the documentation, I get the following error:

Since this error is in the R SDK docs, I tried with NO_SDK=1, but that just moves the problem:

For what it's worth, I also get these warnings at the start of the run:

Calling `DidYouMean::SPELL_CHECKERS.merge!(error_name => spell_checker)' has been deprecated. Please call `DidYouMean.correct_error(error_name, spell_checker)' instead.
