test: pin func CLI version so config ci workflow test is deterministic (#4034)

The integration test asserted the generated workflow contains
github.DefaultFuncCliVersion, but the command now sources the version
from version.Kver (injected via -ldflags). On release-1.23 the branch's
latest tag is knative-v1.23.1, so the emitted version did not match the
compiled-in default (knative-v1.23.0) and the test failed. Pin
version.Kver in the test so the output is independent of the build/branch.
