Command "translation:extract" is not defined.

Expected Behavior

It should be possible to extract translations from twig files with the following command according to the docs.

bin/console translation:extract en --dir=./src/SWP/Bundle/FixturesBundle/Resources/themes/DefaultTheme/ --output-dir=./src/SWP/Bundle/FixturesBundle/Resources/themes/DefaultTheme/translations

Current Behavior

But I get the following output when running translation:extract:

Command "translation:extract" is not defined.

Do you want to run "translation:update" instead?  (yes/no) [no]:

And the output from php bin/console list don't mention the translation:extract command. It only lists the translation:update command.

translation
  translation:update                         Updates the translation file
