Incorrect bundle paths when bundles are in multiple directories.

[Undistraction]

Issue description

Where bundles are output to more than one directory, bundle paths are incorrect.

I'm using webpack-bundle-analyser with Gatsby via gatsby-plugin-webpack-bundle-analyser-v2 which is a very thin plugin. Gatsby adds bundles to /public/, however another plugin I use gatsby-plugin-netlify-cms adds bundles to /public/admin/. When BundleAnalyzerPlugin derives the bundleDir it resolves (using this.compiler.outputPath to /path/to/public/admin/ which it then uses as a prefix for all bundle paths. This means only the bundles that are generated to /admin/ are correct. The rest are not and result in warnings:

Error parsing bundle asset "/Users/me/Sites/www/public/app.js": no such file

It seems the current architecture can't handle situations where bundles are in written to different locations.

Hmm this does sound complicated and a likely bug. Would you be able to create a small reproduction so it would be possible to fix this at some point?

Hi, I can confirm this.

Here a part of json I have:

"children": [{
		"hash": "acbf87df4bf149c73cd1",
		"version": "5.65.0",
		"time": 28955,
		"builtAt": 1652089618297,
		"publicPath": "/assets/static/",
		"outputPath": "/app/public/assets/static",
		"assetsByChunkName": {
			"static:fonts": ["style/fonts-acbf87df4bf149c73cd1.css", "js/fonts-0a26b8e32bf029c9d244c1cd344336a5.js"],
			"static:pdf-availability": ["style/pdf-availability-acbf87df4bf149c73cd1.css", "js/pdf-availability-6a5493c1496fd7e44b08a976c90cd01a.js"],
			"static:pdf": ["style/pdf-acbf87df4bf149c73cd1.css", "js/pdf-801d6111f8a308117ba0f8c07cc16d37.js"]
		},

Warning for the file:

Error parsing bundle asset "/app/public/assets/js/pdf-availability-6a5493c1496fd7e44b08a976c90cd01a.js": no such file

It seems it ignores the publicPath ?

Please create a small reproduction case
