Document the browser-use plugin and browser extension for enterprise security review #5389

The CLI changelog mentions the built-in browser-use plugin, but the companion Chrome extension doesn’t show a verified publisher badge - https://chromewebstore.google.com/detail/github-copilot/hblomdgalaelcilcdepgohfcogjiijhe I presume this is the extension right?

Could the publisher get verified? That would make it easier to confirm this is an official GitHub extension before granting it browser access.
