Fixes links that return 404 (or no longer resolve), each replaced with the page's current address:

Prettier rewrapped the paragraphs whose line length changed; prettier --check and markdownlint-cli2 pass on the changed files.

Based on 4.4, where the recent docs fixes land; happy to retarget.

Not changed, for a maintainer's call:

• core/errors.md and laravel/index.md link /docs/guides/error-provider/ and /docs/guides/error-resource/, which return 404. Guide pages seem to be published only under /docs/v4.2/guides/ now (/docs/v4.2/guides/error-provider/ works; 4.3, 4.4, 5.0 and main don't), so this looks like a guides-build issue on the site rather than a docs one.
• deployment/heroku.md points to the ClearDB add-on, which is no longer on Heroku.
• deployment/minikube.md links helm/skaffold.yaml and helm/skaffold-values.yaml in api-platform/api-platform, which were removed in CLI scaffolding api-platform#2980; Update Kubernetes deployment guide to match current Helm chart #2272 updates the Kubernetes guide.
• The rabbit picture in core/openapi.md's example description (rabbit.org/graphics/...) is gone, but it's sample content.

I drafted this with help from an AI assistant.
