In confounders, menstrual cycle is now all NaN

[Rahul-Brito]

In '/orcd/data/satra/002/datasets/b2aivoice/2.0-release/2025-04-04T18.14.48.299Z/phenotype/confounders.tsv', there is a column called menstrual_cycle_status. In release 1 internal, we had that information present, but in that document it seems to be all NaNs. Is that intended?

this is the same in the released phenotype.csv in '/orcd/data/satra/002/datasets/b2aivoice/2.0-release/2025-04-04T18.14.48.299Z-derived/phenotype.tsv'

@satra did this field get dropped at some point? @alistairewj
