What happened?

The valid_json language string is missing in /system/Language/en/Validation.php. I can certainly fix this by providing my own string, but given this is a stock validation rule, it probably aught to exist.

Steps to Reproduce

create a validation rule containing valid_json, and pass invalid json.

Expected Output

I would expect to see something like:
The content field must be valid json.

Instead i get:
Validation.valid_json

Anything else?
