[DOCS] Document that cron and splay are supported together #60732
Description
Description
Document that scheduling jobs with both cron and splay is supported/works.
Right now I had to find this issue to check if it was supported as none of the examples show it #44583

Additional context
Would be nice if it was also recommended to use this as otherwise you get very hard to figure out errors like Data failed to compile job is running as PID xxx and a jid which shows nothing. Basically if you have overlapping schedules then one of the jobs will fail to run with a very hard to diagnose error.
