[Docuementation] recurring run parameters to get scheduled time

[Bobgy]

Asked in kubeflow/kubeflow#5014 (comment)

We need documentation on https://kubeflow.org about how to use arguments like [[ScheduledTime]] in recurring runs, currently documented in

pipelines/backend/src/crd/samples/scheduledworkflow/parameterized.yaml

Lines 29 to 34 in 578e823

	# [[ScheduledTime]] is substituted by the scheduled time of the workflow (default format)
	# [[CurrentTime]] is substituted by the current time (default format)
	# [[Index]] is substituted by the index of the workflow (e.g. 3 mins that it was the 3rd workflow created)
	# [[ScheduledTime.15-04-05]] is substituted by the sheduled time (custom format specified as a Go time format: https://golang.org/pkg/time/#Parse)
	# [[CurrentTime.15-04-05]] is substituted by the current time (custom format specified as a Go time format: https://golang.org/pkg/time/#Parse)
	value: "hello world [[ScheduledTime]] - [[CurrentTime]] - [[Index]] - [[ScheduledTime.Mon Jan]] - [[CurrentTime.15-04-05]]"

Hi @Bobgy, here's a good reference for defining the time format
https://programming.guide/go/format-parse-string-time-date-example.html
According to this doc, I successfully got scheduled time in %Y-%m-%d format with [[ScheduledTime.2006-01-02]] as the macro.
