Clean up VirtualBox demo appliance residue (#354282)

- `androidenv.androidPkgs_9_0` has been removed. It is replaced with `androidenv.androidPkgs` for a more complete Android SDK, including support for Android 9 and later.

- The VirtualBox demo installer appliance has been removed.

  Please use the standard installer ISOs instead.

- `grafana` has been updated to version 11.1. This version doesn't support setting `http_addr` to a hostname anymore, an IP address is expected.

- `deno` has been updated to Deno 2, which has breaking changes.
