/**
 * Creates a resolver function for validating form values using a Zod schema.
 * The type of form values is automatically inferred from the schema.
 *
 * @template TSchema - The Zod schema type.
 * @param {TSchema} schema - The Zod schema to validate the form values against.
 * @returns {TResolver<T>} A resolver function that validates the form values and returns validation errors, if any.
 *
 * The resolver supports validating either the entire form or a single field:
 * - If `fieldName` is provided, only the specified field is validated.
 * - If `fieldName` is not provided, the entire form is validated.
 *
 * The returned resolver function:
 * - Accepts the form values and an optional field name.
 * - Returns an object containing an array of validation errors, or an empty array if validation passes.
