Sync word count with canonical tests

[jonathan-h-grebe]

Summary

This PR syncs the tests for word-count with the canonical data by

• removing tests whose requirements contradict the problem specification as described in instructions.md
  • "hyphens" - this required the solution to treat words containing a hyphen as single words, whereas the instructions state "The only punctuation that does not separate words is the apostrophe in contractions."
  • "German" - this required the solution to handle German script characters, whereas the instructions state "The subtitles from these dramas use only ASCII characters."
  • "Polish - same as with German
• eliminating test description inconsistencies. eg change "count one of each" to "count one of each word"

@angelikatyborska Strictly speaking this change lands outside the scope of the problem this PR aims to fix, but since it is very minor I thought I'd try including it anyway.

I couldn't understand the text here, and from the contents of the test it looked like a typo.
I'm assuming what I've changed it to matches the intention of the test, but please tell me if I'm wrong!
