Vela show fails to generate parameter on docs generation command for workflow definitions containing imports

Describe the bug Vela show docs command does not generate parameters from the definitions into the docs if the definition contains external cue packages.

To Reproduce Apply sample workflow definition to the cluster:

import (
	"vela/kube"
)

testwf: {
	alias: ""
	annotations: {}
	attributes: {}
	description: ""
	labels: {}
	type: "workflow-step"
}

template: {
	configMap: kube.#Read & {
		$params: {
			value: {
				apiVersion: "v1"
				kind:       "ConfigMap"
				metadata: {
					name:      "test"
					namespace: context.namespace
				}
			}
		}
	} @step(1)

	parameter: {
		foo: string
	}
}

Run the following command to generate the docs: vela show testwf --format markdown

The markdown generated does not contain the description or any mention about the parameters. Removing the imports fixes the issue.

Expected behavior Vela show command should generate parameters table with description.
