Use to_sentence to show list of methods without using I18n

This code was introduced by rails#17221 to workaround issues with not having
the `:en` locale set in the app to translate when calling `to_sentence`,
when having `I18n.enforce_available_locales` enabled.

We can still use the helper, with the defaults provided by the code,
without using I18n and thus without relying on the app locale, by
passing the `locale: false` option.
