New TelemetryEvent cannot handle nested array as $body argument #648

I'm using the newest release of the Laravel PHP package which uses the 4.1.0 version of this package. This version can result in the following error:

Named parameter $message overwrites previous argument {"exception":"[object] (Error(code: 0): Named parameter $message overwrites previous argument at vendor/rollbar/rollbar/src/Payload/TelemetryEvent.php:50)

This error is thrown if the body argument of the TelemetryEvent __construct function is a nested array. For example (when using the Laravel-Rollbar package):

Log::info('This throws an error', [["data" => "some data]]);

The error is caused by the top-level nested array. This worked before, so this is regression of functionality.

Simple replication
To replicate you can do the following, which is simple direct replication of what happens in the constructor of the TelemetryEvent class.

// This throws an error
$event = new TelemetryBody(...[['data' => 'some_data']]);

One lever higher up, there is a restriction on what is allowed in the array of the body. The following will cause an error:

new TelemetryEvent(
      EventType::Log,
      EventLevel::Info,
      ["0" => ["id" => "some id"], 'message' => 'test message'],
 );

The above is a simplification of how the TelementryEvent is used within Rollbar-Laravel package: https://github.com/rollbar/rollbar-php-laravel/blob/f430c09887d3603bcefc870fd7a9e7abcd009920/src/TelemetryListener.php#L104 which triggers this issue.
