Support for the Pint exclude config

[N1ebieski]

Fix #517

When a user has pint.runOnSave enabled and saves the current file, the extension uses: vendor/bin/pint path/to/the/file.php. When we add a specific file to the command, then Pint ignores the exclude configuration even if this specific file (or its path) is listed in the pint.json config file.

It's a Pint issue, but we can handle it in the extension before executing the command.

This PR adds support for all Pint "excluding" configs: https://laravel.com/docs/12.x/pint#excluding-files-or-folders

@N1ebieski thanks for the contribution!

I made one small change: we now exclude files only for auto-save runs. If a user explicitly runs Pint on a specific file, they can still do that even if it's excluded in pint.json. This matches Pint's default behavior.
