Pipeline triggers multiple Jobs

I added a very basic `.drone.yml``to see if it works.

---
kind: pipeline
type: docker
name: default

clone:
  disable: true

steps:
- name: greeting
  image: alpine:3.12.0
  commands:
  - echo "hello $(whoami)"

But whenever I push a single commit into the master branch, the job will be started twice.

  runner:
    image: drone/drone-runner-docker:1
    restart: always
    environment:
      DRONE_RPC_PROTO: https
      DRONE_RPC_HOST: drone.some.domain
      DRONE_RPC_SECRET: ee49eaa0ecaf3a2acc2ef9f831648efd
      DRONE_RUNNER_CAPACITY: 1
      DRONE_RUNNER_NAME: docker-runner
    ports:
      - '3000:3000'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

Drone triggers a pipeline for each webhook it receives from Gitea. If multiple pipelines are triggered it means multiple webhooks are being sent from Gitea. Make sure only a single webhook is configured for your repository in Gitea and remove any duplicates. If the issue persists, please contact the Gitea community support team to investigate multiple webhook delivery issues and possible regressions.
