[ Enhancement ] Ability for Startups to be deleted from the Admin Dashboard

[daviskeene]

Description

To remove a startup from the directory, this must be done manually by deleting the corresponding mongo document. Let's add a feature to the Admin Dashboard that allows us to do this in the app instead.

Steps to Solve

1. Create an API route that will delete an org with a given id.
2. In the admin dashboard, create a wrapper that allows us to delete startups.
3. Test!

Definition of Done

This issue will be marked as Closed when a PR is approved that accomplishes the following:

• An organization can be deleted from the Admin Dashboard, as opposed to manually deleting the mongo document.
