NRC Recipe is broken due to missing import

[tbloemen]

When I want to run the NRC Handelsblad news fetching service, the internal recipe imports calibre.web.jsbrowser. This dependency is not found by calibre. I have tried the version from the website and the flatpak version, in both versions it is not bundled, which breaks the news recipe.

Spoiler:

Calibre version: 8.9
OS: Linux

Complete stacktrace:
calibre, version 8.9.0 (linux, embedded-python: True)
Conversion error: Failed: Fetch news from NRC Handelsblad
