Securely call Webhook endpoint after your Action finishes

Sending a json string, url, and hmacSecret are required fields, and data is optional.

- name: Webhook
  uses: navied/secure-actions-webhook@0.2.0
  with:
    url: https://example.com
    data: '{ "example": "data" }'
    hmacSecret: ${{ secrets.HMAC_SECRET }}

The request will include the header X-Hub-Signature, which is the hmac signature of the raw body just like in Github webhooks, and also the header X-Hub-SHA which is the SHA of the commit running the github action.

Verify it on your endpoint for integrity.

Thanks to https://github.com/koraykoska/secure-actions-webhook for providing the base signature generation code.
