Additional EU vat rate fixes

[brtdv]

After posting a few PR's, (#15, #14, #13) I took the liberty to quickly check some of the other listings and found a few more minor issues:

• CZ uses two reduced rates of 10% and 15% instead of only 15%
• Estonia uses a standard rate of 20%
• Latvia uses two reduced rates of 5% and 12%
• Slovenia uses two reduced vat rates of 5% and 9.5%

I used the EU VAT PDF overview as reference: https://taxation-customs.ec.europa.eu/document/download/28091aa6-62e0-4b27-922c-4f701e2f0ce3_en?filename=vat_rates_en.pdf

The VAT rate in Estonia was raised from 20% to 22% as per 01-01-2024, according to this source. That makes me question the correctness of the document you used for the other rates..

According to europa.eu, which was last updated on 23-03-2022:

• CZ does indeed use two reduced rates of 10 and 15%. ✔️
• EE used a 20% standard and 9% reduced rate, but that was in 2022. I can find several sources reporting about the increase to 22% on 01-01-2024. ❌
• LV does indeed use two reduced rates of 5 and 12%. ✔️
• SI does indeed use two reduced rates of 5 and 9.5%. ✔️

So if you could remove the Estonia change from this PR then I am happy to merge this.

You seem to be correct, I've reverted the EE changes. There do seem to to be multiple reduced rates for EE but I might add these in a separate PR later on.
