fix(tests): Pin ngrok to v2 and use https

[nitrocode]

what

• Pin ngrok to v2 e2e-deps.sh
• Use https proto

why

• v3 became the stable version recently and we haven't updated our scripts yet. This is a temporary change until we upgrade to ngrok v3.
• http proto was deprecated so it returned an empty string

Error with localhost
