The file dist/source-map-resolve.js is missing in the published package

Describe the bug

I got this error after upgrading Rollup from 3 to 4 and replacing rollup-plugin-sourcemaps with rollup-plugin-sourcemaps2:

> rollup -c --environment NODE_ENV:production

[!] Error: Cannot find module '/.../node_modules/rollup-plugin-sourcemaps2/dist/source-map-resolve' imported from /.../node_modules/rollup-plugin-sourcemaps2/dist/index.js
file:///.../node_modules/rollup-plugin-sourcemaps2/dist/source-map-resolve
Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/.../node_modules/rollup-plugin-sourcemaps2/dist/source-map-resolve' imported from /.../node_modules/rollup-plugin-sourcemaps2/dist/index.js

It appears that the file dist/source-map-resolve.js is missing in the published package.

To Reproduce

I got the error in a project, which I can't show publicly, but it should happen in any project, when looking at the content of the NPM package:

❯ npm init -y

❯ npm i -D rollup-plugin-sourcemaps2

❯ ls node_modules/rollup-plugin-sourcemaps2/dist
index.cjs  index.cjs.map  index.js  index.js.map

❯ head -n 4 node_modules/rollup-plugin-sourcemaps2/dist/index.js
import pluginUtils from '@rollup/pluginutils';
import fs from 'fs';
import { promisify } from 'util';
import { resolveSourceMap, resolveSources } from './source-map-resolve';

The last line expected the file source-map-resolve.js in the same directory as index.js. The previous command listing the content of rollup-plugin-sourcemaps2/dist didn't show it.

Expected behavior

Either the file src/source-map-resolve.ts should be transpiled to dist/source-map-resolve.js, or bundled inside dist/index.js.

Environment

• Package Version: 0.3.0
• Node.js Version: 20.15.1
• NPM Version: 10.7.0
• Operating System: macOS Sonoma 14.5 (23F79)
