[Fleet] Don't retry if icon isn't in initial response

[jfsiii]

Summary

closes #66226

Remove tryApi param from PackageIcon, since response is from the Registry already

kibana/x-pack/plugins/fleet/public/applications/fleet/sections/agent_policy/create_package_policy_page/step_select_package.tsx

Line 49 in 5e351db

const [packages, setPackages] = useState<GetPackagesResponse['response']>([]);

Setting tryApi={true} is just flooding the Registry with requests for items we know aren't there.

Compare master (note XHR requests for bluecoat, etc)
