fix: Rebuild SSL policy to account for min TLS version

This change modifies the SSL policy name of the load balancer in front of the Runway service. This will force existing services to delete their old policy and build a new one, which will allow us to implement the minimum TLS version change from !80 (merged), which is currently failing to update in place (e.g. https://gitlab.com/gitlab-com/gl-infra/platform/runway/deployments/ai-gateway/-/jobs/5141811099). Since this is the policy that will be used in our live environments, both production and staging, we change its name to the anyways more approriate production-ssl-policy.
