test: adjust for tag workflow IDs being passed as strings

In 60acf5c (cascading-runs: pass workflow run ID as string, 2023-03-07),
we started passing the IDs as strings because workflow dispatch inputs
_always_ have to be strings.

Let's adjust the tests accordingly, to give them a chance to pass again.
