move mageno 2 locked config back to database

set-config.php

#!/usr/bin/env php

## steps
#
#  fix where app:config:dump was run, adn value sin magento db is outof sync (so they ONLy exist in the dumped configs)
#
# Copy your app/etc/config.php (or app/etc/env.php) to bin folder
# delete from the app/etc/config.php (or env.php) file the values you want to re-import TO DB
# run bin/magento app:config:import (to process the changes you just made)
# run this script: ./bin/set-config.php --config config.php (or env.php)
# The script will process teh config as given, and set the config value to db)
#
# The end result should be all your file based configs to be existing back in the magento config db values
# you cannow doa more selective lock setup, rather than having had it all in the files.
