fix: use dts.bundle: true

[colinaaa]

Currently, the types of rslog does not work with "moduleResolution": "node16" as it's missing .js extension.

// dist/index.d.ts
export { createLogger } from './createLogger';
export declare let logger: import("./types").Logger;
export type { Options, Logger, LogType, LogLevel, LogMessage, LogFunction, } from './types';

This patch solve the problem by enabling DTS bundle.
