[PATCH] sched/doc: Update yield_task description in sched-design-CFS

Patch content 3 changed files

From: fangqiurong <fangqiurong@kylinos.cn> The yield_task description referenced the long-removed compat_yieldsysctl and described the function as a dequeue/enqueue cycle. Updateit to reflect current behavior: yielding the CPU by moving thecurrent task's position back in the runqueue. Sync zh_CN and sp_SP translations.
