bug: `Authorization` header is incorrect

[dyc3]

Summary

The format of the Authorization header that this playbook uses for API requests is incorrect.

The correct format is Authorization: Bearer <token>, as seen in the API docs here: https://docs.github.com/en/rest/actions/self-hosted-runners?apiVersion=2022-11-28

Also, it would probably be a good idea to pin the API version with the X-GitHub-Api-Version header as well.
