typo in documentation for db-merge

on https://prodi.gy/docs/recipes#db-merge :

prodigy
db-merge
news_person,news_org_news_product
news_training

should probably be:

prodigy
db-merge
news_person,news_org,news_product
news_training

the '_' between news_org and news_product should probably be a ','

Thanks and you're right, that's definitely a typo. Appreciate the attention to detail – already fixed it and should be live soon :slightly_smiling_face:
