Delete a Comment Without Creating a New One

[joeyagreco-sb]

Desired functionality:

1. Workflow runs, creating a comment with tag foo
2. Workflow runs again, deletes the comment with tag foo

Current functionality

1. Workflow runs, creating a comment with tag foo
2. Workflow runs again, deletes the comment with tag foo
3. New comment is created in deletion step
   a. Ideally, you would not have to create a new comment upon deletion of another comment

Here's an example workflow snippet

      - name: Post Comment
        uses: thollander/actions-comment-pull-request@v2
        with:
          message: |
            #### hello world
          comment_tag: foo
          mode: recreate

      - name: Delete Comment
        uses: thollander/actions-comment-pull-request@v2
        with:
          message: |
            #### Why do I need this to delete?
          comment_tag: foo
          mode: delete
          create_if_not_exists: false # thought this may fix it (it does not :/)

At the end of this, the Post Comment comment is deleted, but seemingly always replaced with a new comment that has the contents of the message in the Delete Comment step.

Ideally, there would be a way to delete an existing comment without creating a new one.

If there is a way to do this and I'm missing something here, please let me know

Thanks!

Update: seems this functionality may not be supported by GitHub: https://github.com/orgs/community/discussions/26256

After release of 2.4.1, this is not reproduced anymore (thanks to this fix).

What's actually happening is that last comment is created but deleted just after.

The downside still with this approach is that if you have notifications setup to pipe into your company chat like Slack you will get notifications for these placeholder message which get deleted which is a bit confusing
