MLGT-Chinese: Update Chinese sheet metadata

[ronaldtse]

The current Chinese register metadata is a translation of the labels, which is not useful.

( "注册" literally means "registration")

We need to correct the Chinese sheet metadata.

I propose to use the following information to replace what is there. This is from the best of my information.

I removed the "URI" because the domain name "nsdi.gov.cn" seems unresolvable. The new address is http://www.ngcc.cn/, but we will need to wait for the Chinese experts to confirm.

This information is attached in Excel form.
