Fix ts-ignore on ai workflow example

[slinkydeveloper]

I added one ts-ignore in the ai workflow example to unblock myself for the release, but I think this should be investigated:

examples/end-to-end-applications/typescript/ai-image-workflows/src/workflow/workflow_executor.ts

Line 98 in 69533b4

// @ts-ignore

Should @ts-expect-error be preferred over @ts-ignore?
