Unify translations for "rédiger" and "caviarder" with "censurer" (#2972)

"Rédiger" is a literal translation, it doesn't have that meaning in
french. "Caviarder" is not that common.
"Censurer", imo will be more widely understood by french speakers.

I left the tags so it's still easy to find, not matter which term you
use in search.
