[PATCH proxmox-i18n 1/2] ja: remove second plural form

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

As per gettext docs [1] there is a single plural form for Japaneses.
Here we simply leave the plural form and remove what used to be
`msgid[1]`. Note that this used to throw a fatal warning with msgfmt
--check.
