Subject: [PATCH] [core] fix: allow browser globals in config files (#3992)

The config checker previously only allowed Node.js globals, but since
the config file runs also in the browser context, users should be able
to access browser APIs like `document` or `window` when needed.

This was incorrectly flagged as an error by the `no-undef` ESLint rule.
The fix adds browser globals to the allowed globals in the linter
config.

Fixes #3990.
