[Bug] Wrong prefix in the samples

[azngeek]

What are you really trying to do?

Describe the bug

The current samples need to have their own prefix, which is basically the last part of the Namespace of the Activity. At least in this setup.

However, if you do not know, that the LocalActivity-Interfaces uses SimpleActivity as a prefix, any change made to the class Temporal\Samples\SimpleActivity\GreetingActivity will not be respected.

<?php

/**

 * file that was distributed with this source code.
 */

declare(strict_types=1);

namespace Temporal\Samples\LocalActivity;

use Temporal\Activity\LocalActivityInterface;
use Temporal\Activity\ActivityMethod;

#[LocalActivityInterface(prefix: 'SimpleActivity.')]
interface GreetingActivityInterface
{
    #[ActivityMethod(name: "ComposeGreeting")]
    public function composeGreeting(
        string $greeting,
        string $name
    ): string;
}

Minimal Reproduction

1. Change any code in the method Temporal\Samples\SimpleActivity\GreetingActivity::composeGreeting().
2. Ensure that you edited the method in the namespace SimpleActivity!
3. Reset the worker ./rr reset
4. Run php app.php simple-activity
5. You will see that the output comes from Temporal\Samples\LocalActivity\GreetingActivity::composeGreeting()

use Temporal\Activity;

    public function composeGreeting(string $greeting, string $name): string
    {
        return $greeting . ' my code changes ' . $name;
    }
