Copy of the config for migration

I am having trouble finding a copy of my config that will work in a migration to a new setup not using this docker setup. Just trying to have a documented way out in case I need to install locally instead of using docker.

[As shown here](https://docs.pleroma.social/backend/administration/backup/) part of the backup and migration is moving the prod.secrets.exs file, which in this docker project is dynamically configured.

Any help will be appreciated ♥
