Docs: When using self-signed certificate, Chrome doesn't seem to work

[bryanvu]

Perhaps should note that Chrome doesn't allow accessing sites with self-signed certificates. I was able to access the UI with Safari after clicking through some of the warnings. I didn't see a way to do this with Chrome.

This is indeed a pain in the butt in Chrome. The workaround is not advertised much but if you type "thisisunsafe" while viewing the warning screen, Chrome will let you in. This is only an issue on MacOS Catalina due to some changes Apple made.

I struggled to decide whether or not to include this in the README. Google is trying hard to push people to stop using self-signed certs over the internet. This is why I was hesitant to put the workaround in our documentation. I can add it if we agree that it is the best solution.
