cgi released with Ruby 3.0.2 does not match released gem

[headius]

The release of Ruby 3.0.2 shipped changes to the CGI library, including (but not limited to) #4, changes that came from a JRuby contributor. However, Ruby 3.0.2 claims to be shipping the 0.2.0 released gem.

The gem needs to be updated and released.

JRuby only sources gem-based standard libraries from released gems, and when the released gem does not match what the Ruby version claims, we have no way to install the correct library.

Note this will be largely defunct if we get a release out with JRuby support in #9.

@headius Is there still issues for this? I'd support this.

Ruby 3.0 is only security maintenance phase. I'll close this because we can't fix inconsistent files.
