thanks @ddddddanni , overall looks good, just a couple of nits + coverage

PR #7236 adds the feature to measure groups of qubit-wise-commuting Pauli operators simultaneously.
However, the current implementation generates a separate readout circuit for each individual Pauli operator within a group. This leads to non-simultaneous measurements, which is corrected in this PR.
