Annotation: This change as well as the changes in go.sum, vendor/github.com/heimweh/go-pagerduty/pagerduty/event_orchestration_path.go, and vendor/modules.txt is the result of temporarily pointing the provider to a feature branch of github.com/heimweh/go-pagerduty:

 $ go mod edit -replace "github.com/heimweh/go-pagerduty=github.com/alexzakabluk/go-pagerduty@rule-actions-updates"
 $ go mod tidy
 $ go mod vendor

We can merge this change into the base branch and upgrade to the latest go-pagerduty version before merging into https://github.com/PagerDuty/terraform-provider-pagerduty. If we don't merge this change the base branch won't compile since the DynamicRouteTo property will be missing in the API Client.

Annotation: We can't have either dynamic_route_to or route_to required because they are mutually exclusive and a rule will have either one. Hopefully in the subsequent PR we can add a check for a rule to have one or the other.

Annotation: The dynamic_route_to action takes precedence over route_to but we can hopefully add validation for these actions to be mutually exclusive in the subsequent ticket (https://pagerduty.atlassian.net/browse/ORCA-4813).
