feat: Added translations, use locales instead of depending on hardcoded strings. (#65)

## Pull Request Description

Single and hopefully only commit so weblate is up-to-date with last
repository

## Special thanks to the translators 🎉 

@kingu - Noors (Bokmål) (nb_NO)
@alison2033  - Portuguese (Brazil) (pt_BR)
@andreasmolnardev - German (de)
@stanol - Ukrainian (uk)

If I forgot someone let me know!

## Checklist

- [x] If a new package was added, did you ensure it works for all
supported platforms? Is the package also well maintained?
- [x] Did you add localization for any text? If yes, did you sort the
.arb file using ```arb_utils sort <INPUT_FILE>```?
- [x] Check that any changes are related to the issue at hand.
