#' @name excludeContaminatedCells
#' @inherit AcidGenerics::excludeContaminatedCells
#' @note Updated 2023-09-12.
#'
#' @details
#' `excludeContaminatedCells` only filters based on
#' `"Problematic cell line: Contaminated"` metadata in cell line comments. This
#' is less stringent than `excludeProblematicCells` and intentionaly keeps
#' cell lines that are misidentified but not contaminated.
#'
#' @param ... Additional arguments.
