Description

相比于README.zh-CN.md，README.md中afterBuild选项的参数说明错误

/**
 * Hook called after all declaration files are written
 *
 * It will be received a map (path -> content) that records those emitted files
 *
 * @default () => {}
 */
afterBuild?: () => MaybePromise<void>

/**
 * 在所有类型文件被写入后的钩子
 *
 * 它会接收一个记录了那些最终被写入的文件的映射（path -> content）
 *
 * @default () => {}
 */
afterBuild?: (emittedFiles: Map<string, string>) => MaybePromise<void>
