chore: pin debug package to exact version due to npm compromise

[jiexi]

Explanation

The author of the debug package had their account compromised and the attacker published code in this package on version 4.4.2. This PR updates pins this dependency to 4.3.4 exactly, without accepting minor version bumps.

While the MetaMask SDK wasn't directly impacted by this supply chain attack, users of the SDK may have downloaded affected versions of these packages.

Developers should audit their dependencies for malicious packages, and update any packages using npm upgrade/npm override, or yarn up/yarn resolutions
