The system must have curl installed.

The current implementation throws this error:

I believe it can be fixed by this: https://stackoverflow.com/questions/63052127/protractor-node-libcurl-failed-ssl-peer-certificate-or-ssh-remote-key-was-not-o

The CA Certificates should normally be provided by the OS.
I can just include a copy of Mozilla's CA cert bundle, but thats rather uncommon. Moreover, it creates a new dependency to handle.

What system is the bot running on?

Hmm, I tested the PR on my own windows machine, but I'm not sure if the same problem would exist on Heroku. @Haroon96 maybe you can check?

As it turns out, the error is common: https://github.com/JCMais/node-libcurl/blob/develop/COMMON_ISSUES.md
I can add the third option.
