Having git configured to gpgsign commits is interfering with tutorial

[moT01]

From one of our users:

"After starting container, CodeRoad plugin, and starting tutorial, it seemed to not run setup at all (the pop-ups with run commands weren't displayed). After updating rdb-alpha with freeCodeCamp/rdb-alpha#7 setup seems to run, however running tests still fails. When gpgsign option in git config is commented out, everything works fine."

I haven't attempted to replicate this. I will give it a try and post what I find - maybe it's something with the container we are using. I don't think so though. Assuming it's not, CodeRoad could maybe use a check for that - similar to, or along with, the check for a git username and email:

Or perhaps a way around the signed commits. Not sure exactly what is breaking, maybe there's a simpler way around it. It's not a big issue, just thought I would point it out.

I can reproduce it by adding commit.gpgsign = true to my .gitconfig. I'll look into the cause/solution.

The PR in #521 may not resolve the issue, but it will display to the user a clear message of why it failed.
