Fix gizmo names
Fix gizmo names

Commit 5ef62e546f485e5f2798230dcfbea2b4ddecbe6e renamed EditorNode3DGizmoPlugin "get_name" to "get_gizmo_name", but it wasn't done everywhere. Because EditorNode3DGizmoPlugin inherits from Resource, it was then using Resource::get_name() which resulted in null names.

Fixes godotengine/godot#46349
