Remove CDP failed to spawn messaging from snapshot checks

[AtofStryker]

Current behavior

Currently when CDP fails to connect in Firefox, Cypress retries the connection. But this prints out messaging to the console, which can be seen in this CI job

Desired behavior

We should remove this from our snapshot checks in system-tests so we do not get additional flake from this message
