The hooks on `+doom-dashboard-mode-hook` and `+popup-buffer-mode-hook`
will throw an error if centaur-tabs-mode is disabled, which may be the
case if the user disables it interactively, post-startup.
Fix#5196
Buffers have no read syntax and cannot be serialized. This would cause
errors when :ui workspaces users try to restore sessions that contained
buffer lists.
