Change the second return of ckb from fa to en

I've received an e-mail from a prominent contributor of ckb projects
complaining about the return and he said ckb contributors are divided to
Iranian Kurds and Iraqi Kurds which Iraqi Kurds don't understand Persian
and Iranian Kurds don't understand Arabic, even Iraqi Kurds can't understand
Arabic well so as he said English is best return
