chore: downsize sql_planner_extended logical_plan_optimize sample size to 5

[Jefffrey]

on my M4 Macbook pro, it estimates it would take 50 minutes (!) to run the benchmark

datafusion (main)$ cargo bench -p datafusion --bench sql_planner_extended logical_plan
   Compiling datafusion-common v54.0.0 (/Users/jeffrey/Code/datafusion/datafusion/common)

Warning: Unable to complete 100 samples in 5.0s. You may wish to increase target time to 3077.4s, or reduce sample count to 10.

and running it via the bot just times out: #23215 (comment)

so might actually be useful to reduce the sample size so it can actually run and be of use to us

Makes sense to me, thank you.

This micro bench takes 30s to run, 10 samples still takes a lot of time. Perhaps we can do 5? The result should not be very noisy since it's a very long-running bench case.

i agree, downsized to 5 👍
