gender_inclusive() and sex_inclusive() do not use probs stated in docs

The documentation for `gender_inclusive()` and `sex_inclusive()` implies that these probabilities are used for the `x` values:

| Gender | Percent |
| :-- | :-- |
| Male | 51.07 % |
| Female | 48.63 % |
| Trans* | 0.30 % | 

However, instead, all options are given equal weighting. Data is also only provided for gender_inclusive() and not sex_inclusive().
