[FEAT]: Return run ID from workflow dispatch

[jamesc-skyward]

Describe the need

GitHub recently updated the workflow dispatch API to return run IDs: https://github.blog/changelog/2026-02-19-workflow-dispatch-api-now-returns-run-ids/

It would be nice if octokit.net would be updated to return this value as well.
