[cli] Redirect debug information to stderr

[3vilhamster]

What changed?
I'm redirecting debug information about fetched workflows to stderr, so that stdout information could be piped to tools like jq.

Why?
Customer reported broken flow

cadence wf lisall --query ... | jq '.[].WorkflowID' -rc

Current print causes broken json output.

How did you test it?
Run local

Potential risks
None
