Use sentence case for summary labels (#4617)

str.title() title-cased every label word, which is wrong outside
English: it turned the Ukrainian "Ім'я хоста" into "Ім'Я Хоста" and
broke acronyms ("NTP" -> "Ntp"). The source strings and their
translations are already written with the correct casing.

Capitalize only the first letter of each label instead.
