Increase Sleep Duration in Runtime Executor Starvation Test to Prevent False Positives

[GagaLP]

This PR increases the sleep duration in the runtime executor starvation test to reduce the likelihood of false positives caused by timing-related variability, as seen in this CI run.

The longer sleep ensures that the test reliably captures the starvation scenarios and being less prone to scheduling delays.
