In the Brave News V2 UI you can't unfollow direct sources.

[fallaciousreasoning]

1. Enable Brave News V2
2. Follow a direct source (I like https://reactjs.org/)
3. Try and unfollow the source

Expected
The source is unfollow

Actual
Nothing happens

Detail

I think this is being caused because we treat DIRECT sources differently to COMBINED sources, so setting a DIRECT source to NOT_MODIFIED is like leaving it as enabled. To fix, we should set the direct source to be DISABLED

The above requires 1.46.81 or higher for 1.46.x verification 👍
