Reference to external module when bundling jsdom

What version of Bun is running?

1.1.27+267afa293

What platform is your computer?

Darwin 24.0.0 arm64 arm

What steps can reproduce the bug?

Bundling a script depending on jsdom is broken. To reproduce:

bun install jsdom

# create the script
cat << EOF > jsdom.js                               
import { JSDOM } from 'jsdom';
console.log(JSDOM);
EOF

# bundling
bun build jsdom.js --target=node --outfile=bundled.js

# running (it works)
bun run bundled.js
# > [class JSDOM]

# but it reference an external file read from node_modules/jsdom. Removing this file breaks the bundled script
rm -r node_modules/jsdom
bun run bundled.js
# > error: Cannot find module "/Users/mquandalle/myproject/node_modules/jsdom/lib/jsdom/living/xhr/xhr-sync-worker.js" from "/Users/mquandalle/myproject/bundled.js" 

The error is caused by the following line in the bundled.js:

  var syncWorkerFile = __require.resolve ? __require.resolve("/Users/mquandalle/myproject/node_modules/jsdom/lib/jsdom/living/xhr/xhr-sync-worker.js") : null;

What is the expected behavior?

Maybe similar to #14009 and #11959

It should either copy the file alongside the generated index.js like @vercel/ncc does or directly embed the content inside. Worst part is that the link is an absolute path, so if that build was done in another machine, it will use the absolute path of it and is not runnable in any other environment.
