Be able to use merge-me-action from a workflow_run event

[sbrunner]

What do you want to achieve?

It should be possible to lunch the action on a workflow_runaction, with workflow like this:

name: Auto merge Dependabot updates

on:
  workflow_run:
    workflows:
      - Workflow 1
      - Workflow 2
    types:
      - completed

jobs:
  auto-merge:
    name: Auto merge
    runs-on: ubuntu-latest
    steps:
      - name: Auto merge
        uses: ridedott/dependabot-auto-merge-action@master
        with:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

In this case, we get an event like this (from github context) (largely simplified):

{
  "event_name": "workflow_run",
  "event": {
    "action": "completed",
    "workflow_run": {
      "conclusion": "success",
      "pull_requests": [
        {
          "number": <number>,
          "url": "https://api.github.com/repos/<org>/<repo>/pulls/<number>"
        }
      ]
    }
  }
}

What is the current way of working?

Actually, the merge is done by Dependabot v1

How much does it hurt?

I can't migrate to Dependabot v2, and the solution of putting merge-me-action at the ends of my main workflow doesn't work well because in some cases I should wait on more than one workflow.

Thank you @sbrunner!

We like this addition, and would gladly accept contribution for this addition!

If not, due to the priorities on our end, we currently do not know where this would land in our planning for us to implement ourselves.

Thanks @rencsaridogan

Sure, I will work on it :-)
