Acceptance Criteria

1. If we detect the local environment the whole prewarmup process should be deactivated

Reproduce the problem ✅

I was able to reproduce this on local

• Set WP_ROCKET_DEBUG to true
• Perform any of the actions that triggers the warmup(activate, clear critical images, upgrade to 3.16)
• See logs

Identify the root cause ✅

We don't bail out here when env is local.

Scope a solution ✅

In Engine\Media\AboveTheFold\WarmUp::Controller
- Add a condition in this method to bail out when env is local.

Update tests.

Estimate the effort ✅
