Add compatibility for remote config files

[kevinpijning]

TLDR; ./vendor/bin/pint --config https://raw.githubusercontent.com/laravel/pint/main/pint.json

The issue

I manage a lot of Laravel projects, and i want my codestyle to be consistent between all apps, but i don't want yet another package to manage.

The solution

Making it possible to allow for remote pint.json files and add this pint command to the composer scripts

{
    "pint": [
        "@php vendor/bin/pint --config https://raw.githubusercontent.com/laravel/pint/main/pint.json"
    ],
}

This way i can easily manage a single pint.json file, on a remote like Github without having to manage a self-created package.

Techy

When i was scanning the source code of Pint, i saw that this was almost already possible, Pint does a. file_get_contents to load the pint.json config file, which also works with remote files. The only obstacle i came across was the file_exists which only works for local files.

At the moment i have a proof of concept version of this working, but I was wondering if the community also feels that this is a nice addition to the pint package, and if the maintainers are open to these kind of improvements.

Let me know what u think, I might open a PR (only if the maintainers are open to it)
