[BUG][TYPESCRIPT-AXIOS] the content must be served over HTTPS

Description

I got the following error when trying to access the api from my react-app:

Mixed Content: The page at 'https://example.com/#/dashboard/analytics' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://api.example.com:443/foo'. This request has been blocked; the content must be served over HTTPS.

I can see that the generated Code looks like this

export const BASE_PATH = "http://api.example.com:443".replace(/\/+$/, "");

while the host-property in the swagger.json looks like this:

{
	"swagger": "2.0",
	"info": {
		"description": "Api Documentation",
		"version": "1.0",
		"title": "Api Documentation",
		"termsOfService": "urn:tos",
		"contact": {},
		"license": {
			"name": "Apache 2.0",
			"url": "http://www.apache.org/licenses/LICENSE-2.0"
		}
	},
	"host": "api.example.com:443",
	"basePath": "/",
	"tags": [ ... ]
	...
}

openapi-generator version

4.1.2

Command line used for generation

openapi-generator generate --input-spec swagger.json --generator-name typescript-axios --output gen/api --config api.json

```json
{
	"npmName": "typescript-fetch-api",
	"npmVersion": "1.0.0",
	"snapshot" : false,
	"supportsES6": false,
	"modelPropertyNaming": "original"
}

Suggest a fix

I think that in the swagger.json the notation of :443 is important that the generator would know that it should be served as https. But then it would make more sense to actually use https then in the BASE_PATH constant. Otherwise Chrome and maybe other Browsers wont allow a connection to this endpoint from a https resource.

Start by reproducing the typescript-axios generation with the provided swagger.json, command, and api.json, then inspect where the generated BASE_PATH is assembled. Confirm how the swagger.json host value is interpreted and verify that generation produces an HTTPS endpoint for the HTTPS API without breaking other schemes.
