Likely some of the notebook module init code will need to be adjusted.

First reported in quarto-dev/quarto-cli#11013.

Wheee this is awesome 🎉 - Is this in a release so we can bump the dependency back on Quarto itself? If not, do you have a guess as to when that would happen? We'd love to ship 1.6 with this fix, but that's coming up soon, in two to three weeks.

It is in https://github.com/PumasAI/QuartoNotebookRunner.jl/releases/tag/v0.11.5 so updating upstream to that should resolve this for users.
