Grouped root 'docker-compose.yml' container image updates with the other container images. - #3164

Summary

The Container images - All - Major, minor and patch package rule in renovate.json now matches docker-compose.yml in its matchFileNames array alongside .docker/**, .circleci/** and .github/workflows/**, so the four container image pins in the root docker-compose.yml join the same grouped rule as the .docker/** pins.

The rule's matchFileNames never listed docker-compose.yml, even though docker-compose is one of Renovate's enabledManagers and a customManagers regex already tracks the IMAGE: build arg in that file, so every image bump Renovate found there - uselagoon/mysql-8.4 on the database build arg and the database2 image, uselagoon/valkey-8 on redis, selenium/standalone-chromium, and drevops/docker-wait-for-dependencies - fell through to Renovate's defaults: one PR per dependency, with no schedule.

New Lagoon image releases now produce a single grouped PR on the before 3am schedule instead of splitting uselagoon/mysql-8.4 and uselagoon/valkey-8 into separate unscheduled PRs alongside it, and uselagoon/mysql-8.4 - pinned in both docker-compose.yml and .docker/database.dockerfile - no longer updates across two different PRs in the same cycle; no image version, manager, or other package rule changes in this PR.

Changes

• renovate.json: added "docker-compose.yml" to the matchFileNames array of the Container images - All - Major, minor and patch package rule.
• .vortex/installer/tests/Fixtures/handler_process/_baseline/renovate.json: same one-line addition, kept byte-for-byte identical to the shipped root renovate.json since the installer fixture is a snapshot of it.

Summary by CodeRabbit

• Chores
  • Automated container image updates now also cover images specified in Docker Compose configuration, alongside existing Docker and workflow configurations. This extends update coverage to another supported configuration type; no changes to application behavior are included.
