pythonPackages.spacy_models: add more models

This change adds the missing language-specific spaCy models:

da_core_news_lg, da_core_news_md, da_core_news_sm, de_core_news_lg,
el_core_news_lg, es_core_news_lg, fr_core_news_lg, it_core_news_lg,
it_core_news_md, lt_core_news_lg, lt_core_news_md, nb_core_news_lg,
nb_core_news_md, nl_core_news_lg, nl_core_news_md, pl_core_news_lg,
pl_core_news_md, pl_core_news_sm, pt_core_news_lg, pt_core_news_md,
ro_core_news_sm, ro_core_news_md, ro_core_news_lg, zh_core_web_lg,
zh_core_web_md, zh_core_web_sm

I also checked the licenses and fixed them where necessary.
