Wrong commit order for restoring Chinese

[KnorpelSenf]

Before #547 was merged, there were a number of PQs that do not include Chinese translations but still change all other languages.

It would be great to have a single commit to put into TRANSLATING.md which marks the point at which Chinese was removed. If anyone wants to pick it up, all they have to do is to look what changed since that commit. With the current history, it would be 0ef23b6 but then the commit range 48aa702..d4f552c (which happened before) would also have to be applied, as the translations are missing here.

A good strategy to mitigate this is to create 3 PQs:

• restore the repo contents at c2aeeb6 (Reset to c2aeeb6 #549)
• apply 0ef23b6 from Remove Chinese translations #547 (Remove Chinese #550)
• apply all of 48aa702..d4f552c (Apply commits before Chinese was removed #551)
