LGTM

But JFYI @chrishumanitec, this PR is failing with this test humctl resources test-definition --generate with this new file.

Validation error: Unable to parse resource-definitions/template-driver/ingress/ingress-default.yaml
	failed to read: yaml: line 64: could not find expected ':'

Checks are still failing: error executing template: .manifests:31:44: executing ".manifests" at <.driver.values.routePaths>: range can't iterate over ${resources.dns<route.outputs.path}

Looks like the same error that caused @mathieu-benoit to introduce an exception via #120 earlier. TBH I cannot quite pinpoint the root cause - do we need to add this new Definition to the exception as well?

LGTM, thanks @chrishumanitec for the input and the changes 🙏
