Need to update settings.yaml template for logging changes

[dmsimard]

See:

The releases notes say:

- There have been fixes to logging which requires changes to the
  server's settings.yaml or LOGGING configuration. (#367)
  A warning will be printed if the configuration file must be updated
  and it can be updated manually or by generating a new configuration file.

The "new" default looks like this:

---
# This is a default settings template generated by ARA.
# To use a settings file such as this one, you need to export the
# ARA_SETTINGS environment variable like so:
#   $ export ARA_SETTINGS="/home/zuul/.ara-tests/server/settings.yaml"

Maybe we only need to change the default var to match: https://github.com/ansible-community/ara-collection/blob/cfde8262df84676168e1bf23ff65cdbb7fec5098/roles/ara_api/defaults/main.yaml#L152
