fix(ci): Containerized AGW integ test

[crasu]

Health check in containerized integ ci job (#13695) fails because the container is not healthy after the first docker compose up command.

Summary

Without this change the oai_mme container sometimes gets unhealthy as it needs more time than 12s for startup.

Test Plan

Integ test run: https://github.com/crasu/magma/actions/runs/3233203515/jobs/5294753054
