PR #886 (closing #880) added documentation for oxlint.config.ts to the Configuration guide, but the Config file reference page was not updated.

The reference page currently:

• Opens with a NOTE saying "Only the .json format is supported" — which is no longer true
• Shows only .oxlintrc.json examples throughout
• Has no mention of defineConfig or the TypeScript config format
• Does not show how each field looks when written in oxlint.config.ts

Maybe it's worth adding a switcher between different config formats using tabs? Like on https://oxc.rs/docs/guide/usage/linter/quickstart.html#install for switching between npm, pnpm, yarn, bun.
