Breaking API change in #3457459 broke config_sync

I've tested the changes in Merge Request !14 and they do appear to resolve the issue.

How I tested.(with the patch applied)

- I changed the update mode to "Full Reset"
- I ran drush cd-update --update-mode=1
- I saw that the update mode was overridden via the drush command to merge mode.

I removed the patch

- I ran drush cd-update --update-mode=1

I saw The "--update-mode" option does not exist.

Should we keep the type hint of ExtensionPathResolver and make it nullable, ?ExtensionPathResolver ? A symptom of the change in the MR removing the type hint is that you can now pass anything you want the final argument and it works, with a somewhat unexpected deprecation warning:

Passing Drupal\Core\Config\ConfigFactory to the $extension_path_resolver parameter of ConfigCollector::__construct() is deprecated in config_provider:3.0.0-alpha2

I believe that NULL default arguments are also deprecated in PHP 8.4

I think that makes sense.
