ci: fix profile workflow race with build-system check

[greatgitsby]

Summary

• Upgrade lewagon/wait-on-check-action from v1.3.4 to v1.6.0
• Add checks-discovery-timeout: 300 so it waits up to 5 minutes for build-system to appear before giving up

The profile workflow (pull_request_target) can start before the build workflow's checks are registered, causing immediate failure with "The requested check was never run against this ref."
