freebsd-update-server article: Note to translators

[Jason Helfman]

Hello to all,

It would be great if r41161 could be merged into other languagues,
as it is currently broken documentation (links) if not merged. The broken
links are a direct result of not being able to carry out any subsequent
steps in the article to build your own update server.

I have fixed this in English, so please ping me with any questions you may
have.

Thanks!
