[docs-scanner] Broken link format in Extensions API overview

[docker-agent]

File: content/manuals/extensions/extensions-sdk/dev/api/overview.md

Issue

The final link in the overview page has an incorrect format:

See also the Extensions API reference.

This link is missing the leading / that all other API reference links in this directory use.

Why this matters

Readers clicking this link will get a broken link error. All other API reference links in the same directory (backend.md, dashboard.md, docker.md, dashboard-routes-navigation.md) correctly use the format /reference/api/extensions-sdk/PageName.md with a leading slash.

Suggested fix

Change the link to:

See also the [Extensions API reference](/reference/api/extensions-sdk/_index.md).

This matches the link format used consistently throughout the other files in this directory.
