Problems with IJulia

[pat-alt]

This is related to #79, but a slightly different use case.

I'm trying to publish a Quarto book contained Julia code through GH actions. Relying on the default actions doesn't seem to work, because the IJulia dependency is need for jupyter to find the Julia kernel. Following helpful suggestions by @kellertuer (#79) I've got rendering to work, but now the final publish step to gh-pages is throwing me off (in #79 that's not needed, because it's handled by Documenter.jl as far as I can tell).

I've tried to implement it manually here but run in to this authentication error. I have write permissions enabled for the repo and am passing on the token here.

Any idea what I'm doing wrong?

Many thanks in advance!
