Description:

This PR updates the dryRun check to be set for all debug builds. Previously, it was only being set for non-alpha builds, meaning that if you ran a debug alpha build, you were firing real pixels (and in one case, causing a pixel anomaly 😬).

This changes was originally done since the alpha build was always setting DEBUG, but that's no longer true so the dryRun check can be simplified.

Steps to test this PR:

1. Run the alpha build locally and check that pixels are logged, not sent
2. Do the same for the VPN extension, just start the VPN locally and make sure no real pixel calls are made
