Update the CI setup

- use latest version of actions/checkout
- add a job for PHP 8.3
- use PHP 8.2 to run the dev deps job (latest versions of our
  dependencies don't support PHP 8.0 or 7.4 so the previous config was
  not running against the future version of our dependencies)
- add a job running the dev deps with the http_client implementation as
  well
