Use GCC 11 and patch ada library for constexpr compatibility

GCC 11 lacks constexpr std::string support needed by ada library.
Patch ada.h to change constexpr to inline for functions using std::string:
- url::get_pathname, clear_pathname, clear_search, copy_scheme
- url_aggregator::get_pathname, clear_pathname, clear_hostname,
  clear_password, reserve

This allows Node 24 to compile with GCC 11 while maintaining GLIBCXX
compatibility with Ubuntu 22.04.
