Ruby 2.7.1 fails to verify the https://rubygems.org certificate

[philr]

When running bundle update with the pre-installed x86 and x64 Ruby 2.7.1 builds in the Visual Studio 2019 image, I'm encountering the following error:

Could not verify the SSL certificate for
https://rubygems.org/quick/Marshal.4.8/minitest-5.11.3.gemspec.rz.
There is a chance you are experiencing a man-in-the-middle attack, but most
likely your system doesn't have the CA certificates needed for verification. For
information about OpenSSL certificates, see http://bit.ly/ruby-ssl. To connect
without using SSL, edit your Gemfile sources and change 'https' to 'http'.
Command exited with code 17

See https://ci.appveyor.com/project/philr/tzinfo/builds/32931289/job/1thwl11o6qhdwkxw and https://ci.appveyor.com/project/philr/tzinfo/builds/32931289/job/cuys2ga8t3r1qinm.

I've installed the same Ruby versions locally and have not encountered any problems. The ssl\cert.pem file contained within the installation includes the /CN=GlobalSign/O=GlobalSign/OU=GlobalSign Root CA - R3 certificate required to verify https://rubygems.org.
