feat(reactflowUtils.ts): add getMiddlePoint function to calculate the average position of multiple nodes

Browse source 
The getMiddlePoint function calculates the average position of multiple nodes by summing up the x and y coordinates of each node and dividing them by the total number of nodes. This allows us to find the middle point or center of a group of nodes. This function can be used to determine the position of a new node based on the average position of existing nodes.
