Todos/notes:

• Ended up also adding the field "acronym" because submission will not go through without this field. May want to consider adding back-end code to auto assign an acronym to each organization.
• In the organization table, there is a field called stateName and state. The state field is an abbreviated version of stateName. There should be back-end code that populates them both based on the input, as well as the region-id.
• The tag selection in the form is broken and needs to be fixed. I added a TODO in code.
• There is still legacy styling in the form and also no form validation that should be added in the future.

Looks great and allows us to use the UI to create organizations again.
It's not updating the state / country fields in the organization table though. I think we should either fix that in this PR or create a new issue to do so.

EDIT: I updated the create organization endpoint to populate stateName and regionId. This will at least ensure that region admin dashboard will display the correct organizations. There are several fields that still need to be populated and I will create an issue for those.
