Bump wikipedia2vec to solve unicode error
The Unicode errors in zhwiki and fywiki are solved with the new version of wikipedia2vec. Few other packages had to be updated to resolve intermediate errors.
Ran a few languages to check performance:
| wiki | precision | recall |
|---|---|---|
| bnwiki | 0.7205778717406625 | 0.2928261180850556 |
| simplewiki | 0.7849090635803397 | 0.4323563503891373 |
| fywiki | 0.8259000303990968 | 0.4566365731847868 |
| zhwiki | 0.8196185286103542 | 0.0440551861507367 |
simplewiki and bnwiki results remain same, so this is good. zhwiki and fywiki now run successfully and have good results.
