Docs: PingSource(docs/eventing/sources/pingsource.md) source schedule confusion

[lancerdima]

Expected Behavior

Documentation should state that events are produced every minutes. Text should be inline with the samples.

Actual Behavior

Documentation states that events are produced every second.

@lancerdima can you provide some links to where you are seeing this please

Example section:
This example shows how to send an event every second to a Event Display Service.

Running samples from the page indicate that events are generated once in a minute, or once in two minutes
schedule: "*/1 * * * *"
schedule: "*/2 * * * *"

I am not sure about the intended design decisions, but this CRON pattern with 5 fields is for minutes granularity - and behaves accordingly. Attempt to provide 6 fields for seconds granularity, result in an error. This is a bit confusing when taking the first introductory steps with the platform.

@lancerdima got it, pretty sure it's just a typo and should be minute :slightly_smiling_face: thanks
