sequencer: remove bogus hint for translators

When translating error messages, we need to be careful *not* to translate
the todo commands such as "pick", "reword", etc because they are commands,
and Git would not understand translated versions of those commands.

Therefore, translating the commands in the error messages would simply be
misleading.
