[sdk] KFP SDK fail to use argo CLI >=2.12 to lint workflows

[Bobgy]

What happened:

After #5266, I noticed in tests, the warning

Cannot validate the compiled workflow. Found the argo program in PATH, but it's not usable. argo v2.4.3 should work.

What did you expect to happen:

KFP SDK can use latest argo CLI to validate workflows locally.

Environment:

KFP SDK version: 1.4.0

Anything else you would like to add:

[Miscellaneous information that will assist in solving the issue.]

/kind bug

/area sdk

The root cause seems to be that, KFP SDK tries to lint empty input using argo CLI to verify if argo CLI works.

However, the default behavior of Argo CLI changed, it gives an error when validating empty string.

We should update to validate an empty workflow instead.
