Deploy Edge-Optimised, Regional or Private gateway API

## Prerequisites

* [x] I am running the latest version. (`up upgrade`)
* [x] I searched to see if the issue already exists.
* [x] I inspected the verbose debug output with the `-v, --verbose` flag.
* [x] Are you an Up Pro subscriber?

## Description

I would like to request the possibility of specifying the endpoint type for the API Gateway; the currently supported values are Regional, Edge-optimised and Private.
As far as I can see apex-up creates Edge-Optimised endpoint by default

The documentation for Regional and Private API are here:
https://docs.aws.amazon.com/apigateway/latest/developerguide/create-regional-api.html
https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-private-apis.html

I have the use case where I want to create an API Gateway that takes requests from multiple EC2 instances, which are located in the same region, so it makes sense to a Regional API.
