test: [M3-8454] - Cypress test for Secure VMs firewall generation

[hkhalil-akamai]

Description 📝

Add Cypress tests to verify the flow to generate compliant firewalls in the Linode Create form.

This flow can also be initiated from the banners in FirewallLanding and FirewallDetails but since those are already covered by unit tests, and the component is shared, I decided to only write tests for generating firewalls through the Linode create flow.
