Hi @Szpieg0. Thanks for your pull request.

The translation work for this project is done exclusively on Transifex:

https://www.transifex.com/arduino-1/ide2/dashboard/

The files under the i18n folder in this repository are automatically generated from the data on Transifex, so any changes made directly to the files here would only be overwritten on the next sync.

For that reason, I can not accept this pull request, but please feel free to contribute any translations via Transifex. Thanks in advance.

More information about participating in the Arduino IDE localization effort is available from this guide:
