Releases for Layout Builder Kit

* Works with Hook Event Dispatcher 4.x
* Contains fixes for PHP 8.2

This major branch:

• bumps Hook Event Dispatcher to version 4, which will make it incompatible with projects that have modules using HED 3
• will be where experimentation with Single Directory Components occurs
• will be where new features are developed.

Due to these dependencies, this major version branch (3) will require Drupal 10.1 and above. If a project can't upgrade to HED 4 or needs to run on Drupal 9.5 for a little longer, version 2 branch is the solution.

Layout Builder Kit 2.0.0-alpha1, 2022-12-05
------------------------------------------
Changes since 2.0.0-dev (2022-11-16):
- It looked like the ThemeHookEvents::THEME constant wasn't available (see
https://www.drupal.org/project/layout_builder_kit/issues/3282326) however the problem was transient for me.
Might still need to use $events['hook_event_dispatcher.theme'][] = ['themeEvent'] but we'll see.

Dev release for testing.
