Add Support to Laravel 10 and Twig 3

[dbpolito]

Seems to be working fine on both versions.

I'm already using my forked version, in case someone needs this right away, you can add to your composer:

    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/dbpolito/document-templates"
        }
    ],

"42coders/document-templates": "dev-laravel_twig_upgrade",
