Wrong example cron string in Data Science Pipelines scheduled recurring run

Description of problem:

If you create a Scheduled run for a pipeline, when selecting Run type = schedule recurring run
we find this value: 

cron =  0 0 0 * *

But this is not correct, as the format needs to be compatible with the CRON Expression Format for the Go cron package, which has an extra field for the  seconds at the beginning. So, I think the correct value for the example would be:

0 0 0 * * *

Note: I found a reference to format in the python kfp source code

In addition of fixing the example value, I think it would be very helpful to users:

• To display the current time in the cluster, which is the one that will be used when running the scheduled jobs
• To add a link to the  CRON Expression Format for the Go cron package or to the user docs explaining how to configure scheduled runs (not published yet)
