128 bug of format ae listing -- sex race age

[fukuhiro2023]

This PR fixes a bug by updating ae_listing() to prevent errors that occur when age, sex, or race values are unspecified in the listing.

Example:

devtools::load_all()
adsl <- forestly_adsl[1:100, ]
adae <- forestly_adae[1:100, ]
meta_forestly(
  dataset_adsl = adsl,
  dataset_adae = adae,
) |>
  prepare_ae_forestly(
    ae_listing_display = c("USUBJID", "BMIBL") # AGE, SEX or RACE is not included in a listing
  ) |>
  format_ae_forestly() |>
  ae_forestly()

Also, update roxygen2 params of prepare_ae_forestly() due to duplication. The removed params are covered by @inheritParames.
