Restore Laravel 6 behavior to public visibility for local driver

Fixes wintercms/winter#503

Here's my preferred solution to this.

@driesvints if you have a moment do you recall or have a link to the reasoning behind changing the default from public to private for the local Flysystem driver in Laravel 9?

[driesvints]

@LukeTowers that got changed in Flysystem v3 so you'll have to ask them. Afaik it's a more safe and sensible default. You should always use the same user to handle files.

[LukeTowers]

@driesvints I agree in theory that it's more safe default, the PHP user can access the files but the problem comes when the webserver user wants to fetch them to respond to requests, which is the default used by a few providers, ServerPilot & Cleavr for example.

Any recommendations for how to handle that use case?

[driesvints]

Not really sorry..

[LukeTowers]

Thanks anyways :)
