The Plugin Frontend Sandbox is now deprecated and will be removed in Grafana v13.4

What is changing

The Plugin Frontend Sandbox was a public preview feature which provided an additional layer of security by restricting what plugins could access and modify. Following the public preview period, we have decided not to progress this feature to general availability, and are deprecating it in Grafana v13.3 with the intent to fully remove it in Grafana v13.4. Grafana OSS and Enterprise users with the feature enabled will now see a deprecation warning in the server logs on startup.
