fix(tools/govanity): add a test for the repo URL

This test does an HTTP request to ensure the URL for the repository does
not return an error.

The test tries first to do a DNS resolution to see if we have network
access. When we build the binary in the nix sandbox we don't have
network access, so we don't want to fail in this situation, we only want
to skip.

The test is going to be run before we do a deployment.
