bug#74963: Ambiguous treesit named and anonymous nodes in ruby-ts-mode

Something with whitespace, but not a big problem.

Yes, 'W' with 'diff-kill-ring-save'.  Single keys are still a problem
in visited diff files.

Thanks.  Maybe a helper for other ts-modes will be handy:

  (defun treesit-node-named (node)
    (treesit-node-check node 'named))

to be used like this

  (sexp ,(cons
          (treesit-match-nodes strings)
          'treesit-node-named))
