Add `createGithubSignatureValidator(config)` which can be used
to create a validator used at an ingress for topic `github`.
On top, there is a new `githubWebhookEventsModule` for the new backend plugin API
which auto-registers the `HttpPostIngress` for topic `github` incl. the validator.

Add an event router for GitHub
which handles events from the topic `github`
and re-publishes events under their more specific topic
based on the `x-github-event` metadata
like e.g., `github.push`.
