Automatic github action to update the linked remoted repositories (logic nodes addon, etc) to the last commit weekly

UPBGE: little fixes for github actions

UPBGE: Remove Empty bound type for characters

It seems it is not properly handled in bullet code.
"Fix" for: UPBGE#1965

UPBGE: Add comments + fixes about bge softbody

Fixes:

1. Use of CTX_Data_ensure_evaluated_depsgraph to flush pending updates
   It calls scene_graph_update_tagged if the depsgraph has
   been tagged. It is needed in the case we add an Object with
   constructive modifiers to have the same polygons count/totface than
   in BL_DataConversion when we create the RAS_MeshObject.
2. Use ob_eval->data as Mesh, like in BL_DataConversion when physics
   CcdShapeConstructionInfo::SetMesh is called.
3. Add the bge softbody modifier at the end of the ob->modifiers list
   to deform the result of all previous modifiers.
