Fix hassfest: use description placeholders instead of inline URLs in translations

[Copilot]

hassfest rejects translation strings that contain raw URLs; they must be provided via description_placeholders instead.

Changes

• translations/en.json: Replace hardcoded URLs in step.user.description and step.self_hosted.description with a {docs_url} placeholder that inlines the URL directly:

  "description": "If you need help with the configuration, have a look here: {docs_url}"

• config_flow.py: Pass description_placeholders to both async_show_form calls to resolve the placeholder at runtime:

  description_placeholders={"docs_url": "https://github.com/custom-components/healthchecksio"}
