run versionBumpp function in a mjs file

[honghuangdc]

Describe the bug

Here are the steps to reproduce the error:

1. create a mjs file
2. import versionBumpp from 'bumpp';
3. run versionBumpp function

import { ReleaseType } from "semver";
^^^^^^^^^^^
SyntaxError: Named export 'ReleaseType' not found. The requested module 'semver' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'semver';
const { ReleaseType } = pkg;

I found a TS type declaration ReleaseType in dist/chunk-L3LY4KGC.mjs.

用 import type 就不会打包到 mjs 里去，看起来是 tsup 打包的问题。
@types/semver 声明了这个type，semver 实际上没有导出。

// src > release-type.ts
import type { ReleaseType } from "semver";

但是打包后直接运行 node .\dist\index.mjs 或者 import { versionBump } from "./dist/index.mjs";
会报 Dynamic require of "tty" is not supported，查了下是tsup打包esm时遇到cjs模块生成的require无效

file:///D:/Work/bumpp/dist/chunk-DHK6LOKB.mjs:29
  throw Error('Dynamic require of "' + x + '" is not supported');
        ^
