Laravel 11 support

[Plytas]

Added Laravel 11 support as requested in #55. This also results in increased minimum php version to 8.2 as per Laravel documentation. We should be able to support php 8.1, but only for Laravel 10.

Most changes are from running pint.

Decided to drop Laravel 9 support as it's past it's end of life. Also updated CI to run test on php8.3 too.

@gtmassey this requires a new version of https://github.com/gtmassey/period. I see there's a an open PR for it gtmassey/period#2.

@Plytas I didn't see the original PR on Period, and now I'm messing around with the support. It looks like I will have to drop Laravel 9 support for Period as well, because I can't seem the package to support both L9 and L11 simultaneously, which is a bummer, because I'd like to keep the PHP base support to 8.1+

So, I'll work on adding laravel 11 support and dropping laravel 9 support on Period, which will also impact a few other things. Might take a bit for it to come through, then I'll re-run the tests here and approve the PR.

I'm not sure if this is possible with the different version constraints, but since Laravel 10 supports php8.1, I'm working to see if we can get this package and gtmassey/period to support php8.1 and up, while still supporting Laravel 10 and 11. But I think that it will cause conflicts with Laravel 11.

I updated a few things on composer, and ran pint, but the tests are failing for some reason. I haven't quite figured out why, but the error I keep getting is "Could not construct ApplicationDefaultCredentials" on several tests across the package.
