Make the tutorial text include the code verbatim from a working repo that passes CI. No pasting necessary. Sure you still have to verify that the tutorial text aligns with the code changes, but you don't have to do anything manual to update the code in the tutorial.
As an actual example of this, here's a plugin for Remark that allows us to import specific functions from a rust source file. https://github.com/ratatui/ratatui-website/blob/main/src/plu... If the source code fails to compile, we get a CI error (in the rust checks). If the source code changes in a way where the import is no longer correct, we get a CI error (in the npm checks).
