chore: remove sleep from payload building

[Manav-Aggarwal]

Overview

Removes sleep to allow for payload building, not needed since ev-reth waits for payload building now: evstack/ev-reth#33

Summary of Changes

Hello @Manav-Aggarwal, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've made a small but impactful change by removing an artificial 10-millisecond delay from the payload building process. This sleep was previously in place to ensure the payload was ready, but with recent updates to ev-reth, this wait is now handled internally, making the explicit sleep redundant. This change streamlines the execution flow by eliminating an unnecessary pause.

Highlights

• Removed unnecessary delay: I've removed a time.Sleep(10 * time.Millisecond) call from the ExecuteTxs function within execution/evm/execution.go. This delay was originally introduced to ensure payload building completed before proceeding, but it is no longer necessary as ev-reth now handles this waiting internally.

Code Review

This pull request removes an unnecessary time.Sleep from the payload building process in ExecuteTxs. According to the description, this delay is no longer needed because the ev-reth engine now handles waiting for payload construction. This is a positive change that improves efficiency by eliminating a fixed delay and increases robustness by removing a potential source of race conditions. The change is straightforward and correct based on the provided context.
