Editor: Use different keys in array of translatable strings.

[59696] changed the 'Text' tab of the classic editor to 'Code' but Code was already used as a key in the array of translatable text. Since arrays keys need to be unique, this meant that it is possible for the wrong translation to appear in a locale. Using different keys fixes that.
