The EvictPod function previously returned a bool and an error. The function now only returns an error. Callers can check for failure by testing if the returned error is not nil. This aligns the EvictPod function with idiomatic Go best practices. Also, the function name has been changed from EvictPod to evictPod because it is not used outside the evictions package.
