github integration is not supported for argo rollouts

I am getting index out of the range for accessing the second part of reporURL in [here](
https://github.com/argoproj/notifications-engine/blob/7b9b5d3281e1b52c17b04369de1cda8072d15072/pkg/services/github.go#L193)

I think repoURL is hard-coded to be [.app.spec.source.repoURL](https://github.com/argoproj/notifications-engine/blob/7b9b5d3281e1b52c17b04369de1cda8072d15072/pkg/services/github.go#L46) in here which is argocd only and doesnt support argo rollouts?

Read pkg/services/github.go at the linked lines 46 and 193, starting with how repoURL is taken from .app.spec.source.repoURL and then split. Trace how an Argo Rollouts repository URL reaches this code and define completion as GitHub integration handling it without an index-out-of-range error.

Written by the indexing model from the issue text.
