Bug: typo in the control-gate matrices on the gates tutorial

[vandieren]

Where does the issue happen?

https://qiskit.org/documentation/tutorials/circuits/3_summary_of_quantum_operations.html#Two-qubit-gates

What is the content issue?

The indented block of mathematical notation (CU: |0>...) after "Therefore, under the action of CU, the basis vectors are transformed according to" matches the block further down on the page, but these should be different from each other. The second block appears to be correct, and the first block needs to be edited.
