/**
 * Validates that feature layer fields have appropriate aliases.
 *
 * This function checks if the given item is a feature service and evaluates the presence of field aliases
 * for relevant fields within the provided feature layers.
 *
 * It returns a `ValidationInfo` object containing the validation result, messages, and scoring information.
 *
 * The scoring logic is as follows:
 * - If the item is not a feature layer, the rule does not contribute to the final score.
 * - If there are no feature layers, a message is added and the result is returned.
 * - If there are no relevant fields to check, the rule receives full score.
 * - If none of the relevant fields have aliases, a message is added to prompt adding aliases.
 * - If less than 80% of relevant fields have aliases, a message is added to prompt improvement and half score is given.
 * - If at least 80% of relevant fields have aliases, the rule receives full score.
 *
 * @param item - The item to validate, typically representing a feature layer item.
 * @param featureLayers - An array of JSON objects representing the feature layers published to this feature service to check for field aliases.
 * @returns A `ValidationInfo` object containing the validation result, messages, and scoring.
