What do you think of adding the vulnerabilities of RubyGems itself to ruby-advisory-db?

It would make sure anyone using bundler-audit would get an error, for instance, and would encourage quick upgrading.

It looks like @sho-h opened #298 for this.

Indeed! I missed that one. Closing the issue in favor of the PR. Thanks!
