Cleanup default configuration

In Thunder distribution we are adding configuration testing and validation after distribution is installed. We want to ensure that configurations are always up-to-date with provided default configs and schemas. Here is related ticket: #2854570: Test installed configuration with configurations provided in files.

Problem/Motivation

Currently after install of diff module, imported configuration is not same as provided configuration in yaml files and it should be.

Way to reproduce it:
1. install module on clean installation of drupal + diff
2. install config_update and config_update_ui module
3. with config_update_ui module it's possible to see differences in configuration page
-> after clean install there should not be any difference between active configuration and original configuration (from yaml files)

Proposed resolution

All what is needed is new export of configuration files, so that they are in sync with active configuration.
