Chore: remove PagerDuty (#83)

PagerDuty is unused in this repo and seems to be causing a terraform plan error:

Error: Unable to find remote state
  with data.terraform_remote_state.firefoxapiproxy_incidentmanagement_A7B41226,
  on cdk.tf.json line 505, in data.terraform_remote_state.firefoxapiproxy_incidentmanagement_A7B41226:
 505:       }
