zh-CN format

[747]

The following key only has one plural form in the zh-CN locale now:

kaminari-i18n/config/locales/zh-CN.yml

Lines 6 to 7 in fcb7fd7

	one_page:
	display_entries: "显示 <b>所有 %{count}</b> %{entry_name}"

but since the English file exploits the plural mechanic to contain three different contextual messages:

kaminari-i18n/config/locales/en.yml

Lines 7 to 10 in fcb7fd7

	display_entries:
	one: Displaying <b>%{count}</b> %{entry_name}
	other: Displaying <b>all %{count}</b> %{entry_name}
	zero: No %{entry_name} found

you need the same number of plural options to reflect them regardless of the grammatical plurality (just like zh-TW and ja do).
