mv git submodule electrum-locale from contrib to electrum/locale

- this merges `contrib/deterministic-build/locale` and `electrum/locale`
- it is now once again possible have translations when running from a local git clone
    - which was already possible in the past before crowdin removed their unauthenticated APIs
        - see https://github.com/spesmilo/electrum/issues/9531
    - however, the translations available are the often-old frozen strings from electrum-locale
        - while previously one could just download the latest strings from crowdin
