ESLint Browser Test fails

[mdjermanovic]

The current main branch of @eslint/eslintrc breaks Browser Test in eslint/eslint. Consequently, the ESLint demo won't work.

eslint/eslint#14865 (comment)

How to reproduce locally:

1. Check out the branch from Upgrade: @eslint/eslintrc@1.0.0 eslint#14865
2. Run node Makefile.js karma

The fix might include some updates in eslint/eslintrc repo and/or updates in webpack.config.js in eslint/eslint repo. I tried several approaches and nothing worked (fixing some errors always produces new errors).

I'd suggest reverting #39.

Running node Makefile.js webpack is a faster option.

This is happening because ./lib/linter.js in ESLint is including all of @eslint/eslintrc, including the Node.js-specific functionality. We can work around this by creating a separate entrypoint in @eslint/eslintrc that just exposes what we need in linter for browser-specific functionality.
