paperless: fix OCR lang-pack install (space-separated PAPERLESS_OCR_LANGUAGES)

The compose fed the +-joined PAPERLESS_OCR_LANGUAGE (e.g. hun+eng) into
PAPERLESS_OCR_LANGUAGES (the install list), so the image tried to apt-install a bogus
'tesseract-ocr-hun+eng' → hun pack missing → Django check crash-loop on the default
hun+eng. PAPERLESS_OCR_LANGUAGES must be space-separated; set a fixed superset
'eng hun deu' (verified each installs). Found live deploying paperless on guest 9201.
