emacs-29 c2d95dd00e6: Remove nullptr named node from c++-ts-mode (bug#64818)

[Theodor Thornhill]

branch: emacs-29
commit c2d95dd00e6cb0abaf4e7550f38c8c2c9ca22f2d

    Remove nullptr named node from c++-ts-mode (bug#64818)
    
    The nullptr node was changed from a named node to an unnamed node
    upstream[0], which caused font locking to break. As this is a small
    enough regression, no compat code is required.
    
    * lisp/progmodes/c-ts-mode.el (c-ts-mode--font-lock-settings): Remove
    node no longer in use.
