fix(notebook): send the notebook path to the UI with forward slashes (#1466)

* fix(notebook): send the notebook path to the UI with forward slashes

On Windows a notebook's snapshot and output events carried its canonical
path as `to_string_lossy()` (`C:\a\b.ipynb`), and the UI uses that path as
the notebook tab's identity, while the project tree and editor name the same
file `C:/a/b.ipynb`. NotebookSnapshot.path and NotebookOutputEvent.path are
now IpcPath, like the other path fields on the IPC boundary (#1456 did the
same for Spring route sources and Add to .gitignore).

* chore: regenerate bindings for the notebook IpcPath fields
