[Labs] Automatically append Markdown to issues

This repository contains a GitHub workflow allowing to append a reminder of the Contributing Guidelines for each newly created issue as stated by:

on:
  issues:
    types: [opened]

Thanks to the julien-deramond/update-issue-body GitHub Action, the workflow will append the Markdown sentence to the issue body automatically.

You can see the result in #17 and #18 that have been modified by the workflow.

Steps to install it in your repository

1. Create a new worfklow in .github/worfklows (name doesn't matter)
2. Copy and paste the content of .github/workflows/append-markdown-to-issues.yml in your workflow file and adapt its content to your needs

You can copy and paste this repository's workflow content in your own repository if you want to do the same thing for enforcing your own Contributing Guidelines for example, or adapt it to your needs.
