Doc build is broken

[AlexDaniel]

See https://docs.perl6.org/build-log/ (example). I tried building locally but couldn't reproduce the issue. I am suspecting that d468b66 is the offender but I can't see why. The last successful build was on the parent of d468b66.

@moritz installed newer rakudo and the issue disappeared. I guess it's resolved.

For the record, I did not install a newer rakudo, just cleaned out the build directory. Still, it worked :-)
