NEL tutorial - v2 config

[svlandeg]

Description

Update config to use spacy.EntityLinker.v2 and spacy.HashEmbedCNN.v2.

Oddly enough, this new v2 config doesn't manage to get beyond 33% F-score for the EL, while the previous v1 version easily obtained 83% (looks like a large diff, but the dataset is super small, so it's not that significant.).
