(de) Book: pipelines.md - 404

[muescha]

the page index shows a pipelines.md:

and this link also result in a 404:
https://www.nushell.sh/de/book/pipelines.md

in the code there is a file pipeline.md:
https://github.com/nushell/nushell.github.io/blob/main/de/book/pipeline.md

and this page is available at:
https://www.nushell.sh/de/book/pipeline.html

i think the publishing system should be updated to consume a pipeline.md instead of a pipelines.md

PS:
this problem is also available in other languages of the book
