Add starter rss pack

[but-whythough]

1. Environment

• Device: [s21]
• OS: [Android 13]
• APP: [0.10.1]

2. Describe the feature request

I think it would help new users to have some default lists to start with, I have used https://www.youneedfeeds.com/starter-packs

to get a few feeds to start with and either linking to pages like that or just having those lists as a one click option to add would be a nice feature

Love the app!
