🌱(demo) create dev users and make them doc accesses

To be able to test with dummy data, we need to create
our dev users from the demo and to give them access to
the docs.
The sub is the unicity of the user for our oidc provider,
so we need to know the sub to be able to create
correctly the user, it is why we set the sub
as the email of the user in the realm.json file.
