Preprocess Text: add POS tagging for other languages

**Is your feature request related to a problem? Please describe.**
POS tagging is not available for languages other than English.

**Describe the solution you'd like**
Add UDPipe POS tagger to POS tagging preprocessor.

**Describe alternatives you've considered**
Any other POS tagger. We used to have Stanford, but it required loading .jar files, which I don't think is desirable.

**Additional context**
/

Start by locating the existing POS-tagging preprocessor and reviewing how English tagging is currently configured. Investigate how UDPipe could provide tagging for languages other than English; done means the preprocessor supports the requested non-English POS tagging without the Stanford .jar dependency.
