[docs-scanner] Time-relative language in model-runner _index.md

[docker-agent]

File: content/manuals/ai/model-runner/_index.md

Issue

The page uses time-relative language that will become stale:

Testcontainers for Java
and Go, and
Docker Compose now support Docker
Model Runner.

The word "now" is prohibited by STYLE.md because it goes stale silently. This framing suggests a recent addition rather than stating the current capability.

Suggested fix

Remove "now" and state the capability directly:

[Testcontainers for Java](https://java.testcontainers.org/modules/docker_model_runner/)
and [Go](https://golang.testcontainers.org/modules/dockermodelrunner/), and
[Docker Compose](/manuals/ai/compose/models-and-compose.md) support Docker
Model Runner.
