/**
 * Validates that relevant fields in the provided feature layers have descriptions.

 * This function checks if the given item is a feature service and evaluates the presence of field descriptions
 * for relevant fields within the provided feature layers. It returns a `ValidationInfo` object containing
 * the validation result, score, messages, and scoring factors based on the percentage of fields with descriptions.
 *
 * Scoring logic:
 * - 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, full score is given.
 * - If no relevant fields have descriptions, a message is added and score is zero.
 * - If less than 80% of relevant fields have descriptions, a message is added and half score is given.
 * - If at least 80% of relevant fields have descriptions, full score is given.
 *
 * @param item - The item to validate, expected to be a feature layer item.
 * @param featureLayers - An array of JSON objects representing the feature layers published to this feature service to check for field descriptions.
 * @returns A `ValidationInfo` object containing the validation result, score, messages, and scoring factors.
