We already had some Polish translations, that were currently not
available to users. Adding it here because it helps me debug some
issues regarding language with more than one form.

Even though JS does the `%d` interpolation in `n__` using a string
replacement. This would not be compatible with the ruby
implementation.

Therefore using named variables instead.

That way we can detect incorrect usage before the strings are added to
Crowdin for translation

This would break with an argument error when interpolating using
`sprintf` in ruby.
