[Feature Request] Different notification icon option, due to similarities with emergency alerts

### Before you submit

- [x] I have searched the issue tracker for [open](https://github.com/Droid-ify/client/issues) and [closed](https://github.com/Droid-ify/client/issues?q=is%3Aissue+is%3Aclosed) issues that are similar to the feature request I want to file, without success.
- [x] I'm not requesting app support for a specific repo — that's up to repo maintainers
- [x] I understand this might not get built (Droid-ify is maintained by a single person)

### What's the problem?

I love Droid-ify, and appreciate being notified when apps have updates. That said, the icon that you chose is one that I always associate with a critical alert (whether device related, or an IRL emergency - I work in disaster management). So whenever I pick up my phone and see that icon, I have a moment of panic.



### What would help?

Having The option of an alternate "new updates available" icon would be great. I'm not a graphic designer by any stretch, but something like this? (With or without the eyes).


### Alternatives?

Entirely up to you whether to replace the notification icon, or give the option to change it in settings.

### Anything else?

Thank you for your excellent work here! Droid-ify makes the f-droid experience a **lot** better.
