`cgi/util` will warn on Ruby 3.5. `cgi/escape` is available since Ruby 2.4, but to use CGI.unescape* methods on Ruby 3.4 and earlier, `cgi/util` must still be required. There's only one place in rdoc that uses such a method, so only one place needs to handle earlier rubies. https://bugs.ruby-lang.org/issues/21258
