Summary
This commit updates the minimum rustworkx version to 0.15.0 to pull in the new PyDiGraph.remove_node_retain_edges_by_id() method introduced in that release. This new function is used for the DAGCircuit.remove_op_node() method instead of the
PyDiGraph.remove_node_retain_edges() function. This new method has much better scaling characteristics and should improve the performance characteristics of removing very wide operations from a DAGCircuit.
Fixes #11677
Part of #12156
