[BangleApps Repo] Feature Request: Tag author on issues relating to their app

### Affected hardware version

Bangle 1, Bangle 2

### Your firmware version

2v27

### The bug

With the new author field created by @bobrippling, I thought it would be very handy if a new issue created relating to someone's app automatically tags them. We could achieve this by having a new field in the create issue page that asks for the app ID, and is then able to tag based off of that, maybe with a toggle the user can enable/disable in the create an issue page. Would this be a welcome and useful change, and how difficult/easy is it to implement? I have little to no experience with GitHub actions, so any input is welcome!
