/**
 * A resolver function for validating form values using a Yup schema.
 *
 * @template T - The type of the form values.
 * @param {ObjectSchema<any>} schema - The Yup schema to validate against.
 * @returns {TResolver<T>} - A resolver function that validates the form values and returns validation errors, if any.
 *
 * The resolver function takes the form values and an optional field name as input.
 * If a field name is provided, it validates only that field. Otherwise, it validates the entire form.
 *
 * The function returns an object containing an array of errors. Each error includes:
 * - `path`: The path of the field with the error.
 * - `message`: The error message.
 *
 * If no errors are found, the `errors` array will be empty.
