arara: sage - A Sage(math)-rule for arara

Completely edited!

The normal run of a tex-file which contains sagetex, say

documentclass{report} 
usepackage{sagetex} 
begin{document} 
sage{2^1234} 
end{document}

is

pfdlatex example.tex
sage example.sagetex.sage
pfdlatex example.tex

For Linux this should run in exactly this form.

For Windows you have to compile the sage-part (2nd line) via

C:ProgrammeSageMath8.9runtimebinbash 
        -l C:/Programme/SageMath8.9/runtime/opt/sagemath-8.9/sage 
           -c "os.chdir('<My current working folder>');      
                    load('<my filename>.sagetex.sage')"

(without linebreaks), see here for details.

How to make a shortcut (for Windows and Linux) of this with arara?

My own try sagetex.yaml does not work 🙁
