You need config.js file with such code:
app.translator.plural = function(count) {
return count == 1 ? 'one' : 'other';
};
function processRelativeTime(number, withoutSuffix, key, isFuture) {
var format = {
'm': ['jedna minuta', 'jedną minutę'],
'h': ['jedna godzina', 'jedną godzinę'],
'd': ['jeden dzień', 'jeden dzień'],
'dd': [number + ' dni', number + ' dni'],
'M': ['jeden miesiąc', 'jeden miesiąc'],
'MM': [number + ' miesiące', number + ' miesięcy'],
'y': ['jeden rok', 'jeden rok'],
'yy': [number + ' lata', number + ' lat']
};
return withoutSuffix ? format[key][0] : format[key][1];
};

I suggest you should find extension with language you can understand even a little, and edit this file.
"Show 1 updated discussion" is held by "flarum-pusher" extension, so you need to edit file named flarum-pusher.yml.
