[jasonvarga]

This PR adds support for Laravel 11 to Statamic 5.

• Support Laravel 11
• Drop support for Laravel 9
• Modernize a handful of dependencies:
  • Drop support for composer/composer 1
  • Drop support for league/glide 1
  • Drop support for rebing/graphql-laravel 6 and 8, bump to 9
  • Drop support for symfony/lock 5, bump to 6
  • Drop support for symfony/var-exporter 4 and 5
  • Drop support for symfony/yaml 4 and 5, add support for 7
  • Drop support for voku/portable-ascii 1

To try out Laravel 11 before it's officially released, you'll need to make sure your composer.json has

"prefer-stable": true,
"minimum-stability": "dev"

---

Todos:

• Get everything passing
• Determine if requiring symfony/http-foundation is necessary
• Use proper version of rebing/laravel-graphql (waiting on Relax PaginationType getPaginationFields typehint rebing/graphql-laravel#1132)
• Cache store related tests failing due to [11.x] Send cache name to event laravel/framework#49754
• Shuffle related tests probably failing due to [11.x] Use secure randomness in Arr::random() and Arr::shuffle() laravel/framework#49642
• Document that seed is removed from shuffle modifier
