The setup-nativescript-stackblitz script is not working

If you try to create a new app it is failing to build:
https://nativescript.new/angular

After StackBlitz is starting you see the following errors:

```
npm ERR! code ERR_INVALID_PROTOCOL
npm ERR! Protocol "https:" not supported. Expected "http:"

npm ERR! A complete log of this run can be found in: /home/.npm/_logs/2024-04-08T10_51_11_444Z-debug-0.log
```
