[NL Embeddings] Refine descriptions for Male/Female SVs to better match queries asking for Male/Femal

[jehangiramjad]

Some context in the comments/discussions for: https://github.com/datacommonsorg/website/pull/2642

After getting more alternative descriptions for SVs, certain queries for male/female are getting mixed results, e.g. "tell me about poverty among women" is matching with Count_Person_Male_AbovePovertyLevelInThePast12Months over Count_Person_Female_AbovePovertyLevelInThePast12Months. There are several other instances of this. See https://drive.google.com/file/d/1-6A-xXcRYj50poglis_7rc1P3aqxYf3R/view for some examples.
