Update composer-post-update-cmd.json

Use @php instead of php as in the composer.json of Laravel.

This is not necessary since the use of the "@" symbol suppresses runtime errors. That is, if an error occurs during the execution of any command, it will not interrupt the execution of subsequent commands.

In our case this is not necessary. If we have an error, we need to get it here and now, since further calling the code will not make any sense without the successful result of the previous command.

Although, in the final application, it may indeed not be important to execute these commands, as a result of which errors can be suppressed.

Thank you!

Thanks for clarifying this. My thought was to "sync" this snippet with the official composer.json that is being referenced. And if for some reason we'd need to output errors during development, we could just delete the @.
