feat(ngrok): Adding ngrok

[bruno-blackbird]

Hello,

There is a working implementation of ngrok with caddy as a reverse proxy to automatically map urls from :

https://domain1.test to https://497b85f07962.ngrok.app
https://domain2.test to https://5fc752cab8e5.ngrok.app

It avoid having to change any url configuration in your local environement, the only limitation I found from now is that it does not work with obfuscated urls.

I also created a pull request on wardenenv/images and wardenenv/warden

I wanted to take an aside to mention that I'm incredibly thankful that you included updating the docs as part of your feature PRs! Thank you, I really appreciate it so incredibly much!
