Bug 251741: lang/ruby30: Update to 3.0.0-preview2
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251741



--- Description ---
* Update to 3.0.0-preview2.
* Don't install erb command and its man page.
  files/patch-tool_rbinstall.rb makes bundled gems not installed. And
  it makes erb broken. We should create rubygem-erb port. But
  unfortunately devel/ruby-gems is currently broken with Ruby 3.0.
* Don't create symbolic link for erb and its manpage.
* Install bundler files other than bin/bundle and bin/bundler
