Remove ownership.yaml (moved to central directory)

Remove legacy ownership.yaml (moved to central repository)

This PR removes the legacy ownership.yaml from the repository root. The relocated ownership file can now be found here:

• File: github/github/emergency-pull-request-probot-app/ownership.yaml

---

Why is this changing?

See the centralization plan and discussion here: Durable Ownership Centralization.

Key points:

• All ownership.yaml files are centralized in github/ownership.
• A small set of repos (e.g., github/github, github/github-ui) are exceptions.

What do I need to do?

• No action required for most repos. This file removal does not affect Service Catalog; the source of truth is the central file linked above.
• If your ownership.yaml is auto-generated, please coordinate with the Service Catalog team.

If you have questions, please reply on the discussion above or reach out to the maintainers of the service catalog.
