HTTPS requirement is in place, even on local testing environments.

[georgestephanis]

Describe the bug
Using Studio, due to my local setup, it's more convenient to use localhost routing.

However, this does not allow https connections, so there is a persistent issue where #1061 is preventing setting up Newspack in the flow.

To Reproduce
Steps to reproduce the behavior:

1. Create a site hosted at localhost
2. Install Newspack plugin from zip
3. Try to set it up...
4. See error

Screenshots

Expected behavior
I'd expect if the environment type were local or perhaps development the https requirement would be dropped. Certainly if the host is localhost
