feat(reactflowUtils.ts): add checkEdgesHandles function to validate if any of the handles in an array of edges are not a JSON string

The checkEdgesHandles function is added to the reactflowUtils.ts file. This function takes an array of edges as input and returns true if any of the handles in the edges are not a JSON string. It checks each edge in the array and verifies if the sourceHandle and targetHandle properties exist and contain a JSON string. If any of the handles are not a JSON string, the function returns true. This function is useful for validating the integrity of the handles in the edges before further processing.
