Execute Workflow node improvement: Auto-populate/search list of workflows

The idea is:

Add option to select workflow from a populated list, similar to the one available in the N8n API node’s Workflow → Get operation.

I believe this can use the existing code here: https://github.com/n8n-io/n8n/blob/master/packages/nodes-base/nodes/N8n/WorkflowLocator.ts#L17 probably in the same way the n8n API node does.

My use case:

Simplify authoring workflows that use the Execute Workflow node.

I think it would be beneficial to add this because:

This would remove the need to lookup/copy/paste opaque workflow IDs or URLs, saving time/context switches and reducing the chance of configuring incorrect values for workflow IDs.
