Feature description

In this document:
https://docs.access-hive.org.au/models/run_a_model/run_access-om3/

We have a section on editing access-om3 configurations:
https://docs.access-hive.org.au/models/run_a_model/run_access-om3/#edit-access-om3-configuration

@adele-morrison has requested that we add information on how to change the time-step (users often want to do this when the model crashes -- example).

Issues was originally raised on access-om3-configs by Adele here: ACCESS-NRI/access-om3-configs#1368
