Stop declaring dependency on HTTP::Server::Simple::CGI

[JRaspass]

None of the code actually depends on this module, it is only referenced in the example code in https://github.com/googleads/googleads-perl-lib/blob/master/examples/oauth/authenticate_with_web_flow.pl

Drop the declaration from https://github.com/googleads/googleads-perl-lib/blob/master/Build.PL

Hello,

I'll see what I can do about that. It is one that isn't used very often, so I can see your point on this.

Best,

Closing this as this repo will be archived and all Perl users should (if not already) migrate to the new library for the Google Ads API.
