Set new default settings for orgs

In a discussion with @mbarbero, he suggested that we set the default_repository_permission setting to none for all our GH organizations.

Api docs: https://docs.github.com/en/rest/orgs/orgs?apiVersion=2022-11-28#update-an-organization

default_repository_permissionstring
Default permission level members have for organization repositories.

Default: read

Can be one of: read, write, admin, none

@mbarbero While we are in there, are there any other settings you would like to change for all orgs?
