`meson compile doc-pdf` fails in `all-pdf`

[tobiasdiez]

doc-html works, but something is wrong with meson compile -C build/cp313/ doc-pdf for me.
I am getting many errors like

/home/dima/software/sage/.venv/bin/python3 /home/dima/software/sage/src/build-docs.py --no-pdf-links es/a_tour_of_sage pdf -o src/doc --source /home/dima/software/sage/src/doc

• that's probably where /bin/sh: line 1: all-pdf: command not found comes from.
