Make the module compatible with commerce v3

perhaps the new ‘composer.json’ file needs to be modified, as the module no longer wants to install with commerce v3.

{
    "name": "drupal/direct_checkout_by_url",
    "require": {
        "drupal/commerce": "^2.0"
    }
}

maybe can be :

{
    "name": "drupal/direct_checkout_by_url",
    "require": {
        "drupal/commerce": "^2.0 || ^3.0"
    }
}
