[docs-scanner] Inconsistent policy name for base image freshness policy

[docker-agent]

Files: content/manuals/scout/policy/_index.md, content/manuals/scout/policy/dashboard.md, content/manuals/scout/policy/local.md

Issue

The same policy is referred to with different names across files in the same directory.

In _index.md (lines 34, 60, 62, 113) and dashboard.md (lines 107, 120):

Up-to-Date Base Images

But in local.md (line 198):

| No outdated base images | Base image is behind the latest digest of its tag |

Why this matters

A reader learning about Docker Scout policies would encounter "Up-to-Date Base Images" in the overview and dashboard documentation, but then see "No outdated base images" in the CLI evaluation guide. This inconsistency makes it unclear whether these are the same policy or two different policies, creating confusion when trying to understand and configure policy evaluation.

Suggested fix

Use consistent naming across all three files. Since "Up-to-Date Base Images" is used in two files and appears to be the canonical name (matching the heading style of other policies), change line 198 in local.md to:

| Up-to-Date Base Images | Base image is behind the latest digest of its tag |

Or alternatively, if "No outdated base images" is preferred, update _index.md and dashboard.md to use that name consistently.
