[translations] Web-zh: Updated Chinese (simplified) website translation

[Anthony Fok <anthony.t.fok@xxxxxxxxx>]

Hello all,

Attached are several patches to update the Chinese translation
of LilyPond website (and some related minor bug fixes).
I had already discussed with Ben Luo to avoid duplication of work.

Cheers,
Anthony Fok
