Subject: [PATCH] internal/jsre: pass correct args to setTimeout/setInterval
 callbacks (#32936)

## Description
- Summary: Correct the JS timer callback argument forwarding to match
standard JS semantics.
- What changed: In `internal/jsre/jsre.go`, the callback is now invoked
with only the arguments after the callback and delay.
- Why: Previously, the callback received the function and delay as
parameters, causing unexpected behavior and logic bugs for consumers.
