const.py wrong VAT for german & Cent as "Ct." instead of "c"

[typxxi]

1. wrong VAT in that const.py file line 126: german VAT is 0.19 and NOT 0.23

2. remove the line 125 in const.py which starts with "Unsure about tax rate, correct if wrong"

3. I also suggest to change the unit for Cents in line 131 from "c" to "Ct." a few lines below of the VAT issue

_CURRENTY_TO_CENTS = {"DKK": "Øre", "NOK": "Øre", "SEK": "Öre", "EUR": "Ct."}

4. german translation

Please send a pr to use the German translation if you think it incorrect and for the vat rate.

I will keep the c as indicator for cents. There is no official rules for how it should be used but they suggested both c and Ct in the official documentation https://european-union.europa.eu/document/download/b9fdeae1-dc66-47a7-a902-fb941309e744_hr?filename=publication6336_en.pdf
