gitlab-build-images missing Ruby 3.3.10 image tag (Severity 3)

Problem: The 18-9-stable-ee branch pipelines failed due to a missing container image tag for Ruby 3.3.10 with Git 2.49.

Impact: The 18.9 monthly release was blocked as the required image could not be found. No impact was observed for deployments, feature flags, or the Duo Agentic Platform.

Causes: The pipeline did not pass the correct GIT_VERSION, causing it to reference a container image tag for Ruby 3.3.10 with Git 2.49 that did not exist.

Response strategy: We merged a change to explicitly pass GIT_VERSION in the release environment pipeline for 18.9. The release environment deployment succeeded, and pipelines are now referencing the correct image version. Backport merge requests were prepared for earlier branches as a precaution.
