Remove generic org type from view on django admin

[abroddrick]

Issue description

We had updated the generic org_type to just be the same as org type without the "- Election" indicator; however this was only temporary as we ran migrations to fill with the new org types for approved domains. We now don't need to show this field on Domain, Domain Request and Domain information for any user. We can keep it in the code for filtering purposes such as on reports as it makes filtering by state/intererstate/etc easier than factoring - elections

Acceptance criteria

• remove generic org type from view on django admin Domain information, Request, and Domain (on the individual record pages not from the tables)

Additional context

This field shouldn't show

This ticket originally included removing election office as well but was removed based on Alex's feedback in this thread
