www/ruby-mechanize: update to 2.11.0

pkgsrc change: update dependency

2.11.0 (2024-07-18)

* The accept-charset header is no longer sent.  In early versions of
  Mechanize, circa 2007, this was a common header but now no modern browser
  sends it, and servers are instructed to ignore it.  See #646 for an
  example of a server that is confused by its presence.  (#647) @flavorjones
