Laravel 7.x: Installation error caused by invalid Process() parameter

[larsbo]

Describe the bug
The install command fails with a TypeError caused by wrong Process() parameter usage here (it expects an array as first parameter):

blogged/src/Commands/InstallCommand.php

Line 55 in 4c7d12b

$process = new Process($composer.' dump-autoload');

To Reproduce
Steps to reproduce the behavior:

1. execute php artisan blogged:install in a fresh Laravel 7.x installation.
2. See error

Expected behavior
The execution of composer dump-autoload.

Screenshots
If applicable, add screenshots to help explain your problem.

The error occures at least with Laravel 7.x because it uses Symfony Process 5.x which requires the array usage as descripted here:
https://symfony.com/doc/5.0/components/process.html#usage
