[docs-scanner] Broken CircleCI documentation link

[docker-agent]

File: content/manuals/docker-hub/usage/pulls.md

Issue

The CircleCI link in the third-party platforms section is broken (returns 404):

• CircleCI

CircleCI has reorganized their documentation and removed the /2.0/ versioned path structure. The link now returns a 404 error, leaving users unable to find the authentication instructions.

Suggested fix

Update the link to CircleCI's current documentation structure:

- [CircleCI](https://circleci.com/docs/guides/execution-managed/private-images/)

This is the current location for CircleCI's documentation on using private Docker images.
