Previously this was always firing at the exact interval. Then #6041 changed this so that the first firing was anytime between 1s and the interval to spread out different stores. This tweaks it once more to anytime between interval/2 and interval. It will still spread things out a bit but hit the benchmarks a bit less badly.
Also go back to math/rand instead of math/rand/v2 due to availability in Go versions that we still care about for 2.10.x.
