Filter nodes selection on bone rename notification

[dpalais]

It seems this error appears ever since #79341 got merged. Since BoneAttachment3D is the only consumer of this notification, I made the find_children call more restrictive in its parameters.

Fixes #83148

How are you determining BoneAttachment3D is the only consumer of this notification?

I did a grep search in the Godot source code.

$ git grep _notify_skeleton_bones_renamed                                           
editor/import/post_import_plugin_skeleton_renamer.cpp:                  nd->callv("_notify_skeleton_bones_renamed", vargs);
scene/3d/bone_attachment_3d.cpp:void BoneAttachment3D::_notify_skeleton_bones_renamed(Node *p_base_scene, Skeleton3D *p_skeleton, Dictionary p_rename_map) {
scene/3d/bone_attachment_3d.cpp:        ClassDB::bind_method(D_METHOD("_notify_skeleton_bones_renamed"), &BoneAttachment3D::_notify_skeleton_bones_renamed);
scene/3d/bone_attachment_3d.h:  virtual void _notify_skeleton_bones_renamed(Node *p_base_scene, Skeleton3D *p_skeleton, Dictionary p_rename_map);

Alternatively doing a check that verifies if the node has such method might be preferable.

Superseded by #83986 which should include this too. Thanks for the contribution!
