Add commands to print the default configuration (#1241)

* Add commands to print the default configuration

When updating a software I often want to compare my configuration with the
configuration of the new version. To make this possible atuin can now print
the default configuration.
This also updates the example files with the actual values used as default in
the settings.rs files.

* Changed command name to 'default-config'

* Fixed merge
