[nexus] fix flake in test 5.8.3 Key Increment of 1 With Roll-over (#12473)

Browse Source 
Step 6 of test 5.8.3 requires the DUT to send an MLE Advertisement
reflecting the updated Key Sequence Counter. The previous 10-second
simulation time in this step was occasionally insufficient, as the
default MLE advertisement interval can be up to 32 seconds.

This commit increases the simulation time in Step 6 to 35 seconds
(kMaxAdvertisementTime) to ensure that at least one periodic MLE
Advertisement is captured in the pcap for verification.
