ai-gov: update local balanced default (#26222)

<!--Delete sections as needed -->

## Description

sbx v0.46.0 added `cdn.playwright.dev` to the Balanced preset, which is
also covered in the release notes. Rather than listing what each version
adds and duplicating the release notes, the page now just keeps the `sbx
policy ls` tip so users can check themselves.
