Store actor.id and repo.id for events

Hi @alexey-milovidov,

Is it possible we store `actor.id` and `repo.id` as documented on [GitHub Event docs](https://docs.github.com/en/developers/webhooks-and-events/events/github-event-types#event-object-common-properties)?

So far, we store `actor.login` and `repo.name` only, which is convenient to use but fails to handle repo/user rename case.

The process can be we extend those column first and fill with data identified by event id.
