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.
