Add support for Carbon^3

[mfn]

Summary

Laravel 11 support was recently added via https://github.com/PHP-Open-Source-Saver/jwt-auth/pull/233

Laravel 11 supports both carbon 2 & 3, see https://github.com/laravel/framework/blob/ae2f9413b5bd8637c363e6fafffda31c88e56c9e/composer.json#L39

"nesbot/carbon": "^2.72.2|^3.0",

However, projects running Laravel 11 and also requiring carbon:^3 (or have other dependencies requiring it), cannot install jwt-auth because we still only support carbon^2.

This PR fixes that, see also https://github.com/PHP-Open-Source-Saver/jwt-auth/issues/230#issuecomment-2002016625

Overview of changes

• Runs tests on 8.3 too
• Remove carbon^1 There was no constellation possible which actually used it. Even Laravel 6 with prefer-lowest did install carbon^2, see any random run, e.g. https://github.com/PHP-Open-Source-Saver/jwt-auth/actions/runs/8252381702/job/22571741990#step:11:34

  [PHP 7.4] [Laravel 6.* - prefer-lowest] … - Locking nesbot/carbon (2.31.0)

• Add support for carbon^3 Carbon 3 has some breaking changes and one of them affected the Method diffInRealMinutes we call from \PHPOpenSourceSaver\JWTAuth\Blacklist::getMinutesUntilExpired

  • the result was negative, i.e. -2…
  • the result was a float, i.e. had a decimal point: .9…

  The change using round() and adding a 2nd arg true keeps the code BC. Without the fix, tests in \PHPOpenSourceSaver\JWTAuth\Test\BlacklistTest would fail
