docs: update vitest config to match vitest docs (#3037)

* Update testing.md in vite, mergeConfig accepts only config in object form. If you have a config in callback form, you should call it before passing into mergeConfig. You can use the defineConfig helper to merge a config in callback form with another config: https://vite.dev/guide/api-javascript.html#mergeconfig * Fix formatting --------- Co-authored-by: Danilo Britto <[email protected]>
