bug#46333: sbcl-common-lisp-jupyter does not install kernel.json

[Jack Hill]

Sharlatan,

Thanks for your recent work updated sbcl-common-lisp-jupyter. I was 
wondering if you had any thoughts on the best way to install the 
kernel.json file [0]. The last time I looked at it, I wasn't sure what the 
best solution would be. Do you have any ideas?
