String addition in gtk+

[Carlos Soriano <csoriano protonmail com>]

Hello,

There was a string not marked for translation. Specifically, in gtkplacesview.ui:

"ftp:// or ftps://"

Since this is a forgotten string, the string freeze break exception is automatically accepted and I just marked for translation and pushed the fix for gtk+ and Nautilus.

Bug report: https://bugzilla.gnome.org/show_bug.cgi?id=771666

Best regards,

Carlos Soriano
