fix(i18n): three Danish strings that had no æ, ø or å in them

Spotted on the running instance: the version line read "Running v0.11.0. Der
bliver ikke set efter opdateringer." — half translated, on one line.

The sweep that was supposed to catch these grepped for Danish letters, and none of
the three survivors contain one: "Ingen nyere version fundet.", "Ikke mere i dag."
and a token hint split across two source lines so neither half looked like prose.

So there is a test for it now. It reads the templates and looks for the words that
give Danish away whatever letters they are spelled with — a word list rather than a
language detector, because this ships as one static binary and thirty common words
catch the sentences a person actually writes. It fails on the exact three that got
through.
