Fix pipeline for creating vocab with gensim 4.1.2

[sandertan]

Hi @w-is-h , gensim 4.1.2 in MedCAT 1.2.0 introduced some changes to the Word2Vec() class which caused MedCAT to crash during creation of the vocabulary. Our medcat-model-creator integration test picked this up. I'll try to create a separate PR to port this creator & tests to MedCAT next week, as discussed in #116

I renamed the parameters in add_vectors() to match the names in Word2Vec. Let me know if you'd like to keep the old MedCAT names.

Changes in Word2Vec

Also, I'm not sure whether class SpacyHFTokis still being used, but it also contained an incompatibility with the new gensim so I updated it.

Tutorials also need an update for new Word2Vec parameter names, e.g. size to vector_size:

Looks good, thanks for the fix

Not used anymore, we have to cleanup some things, will be done soon
