title: Create a GitHub task list issue which automatically lists issues with a specific tag
body: <p>I've googled this and read the GH documentation and can't see anything. I'm guessing it can't be done automatically but can probably be done with an action (which I have very limited experience with).</p>
  <p>I would like to have an issue which automatically populates <a href="https://docs.github.com/en/issues/tracking-your-work-with-issues/about-task-lists" rel="nofollow noreferrer">a task list</a> with any issues which are tagged with a given label.</p>
