ownership.yaml: Surface inactive data for replacement

[github-service-catalog]

Hello.

There exists inactive data in this repo's ownership.yaml file, which gets pulled into the Service Catalog.

What do we mean by inactive?

• For owners (maintainer, team, exec_sponsor, product_manager), it means "not an employee anymore".
• For teams, it means "team doesn't exist in https://github.com/orgs/github/teams, or the team has no members".
• For Slack channels, it means "channel is archived".
• For PagerDuty escalation policies it means "escalation policy has been deleted, or the link is not an escalation policy".
• For repositories it means "repository has been archived, deleted, has become inaccessible to the catalog or has had issues disabled"
• For dependencies, it means "this service doesn't exist".

What should you do?

Please replace the lines containing FIXME with appropriate new, active data. For Slack channels, a public channel is preferred so that people can find your team and ask you questions if needed. For additional recommendations and examples, check out the "service ownership" page on the Hub.

If you need help, please ask questions in #service-catalog on Slack. Thank you for helping us to keep Service Catalog data accurate! 🙇
