Notifications: shove dependabot to a different tab #4523

Not sure, if related: #3090 (dashboard, not notifications).

I watch some repos for PRs. I'm not a maintainer of the repo. I can't merge them or similar.

My notifications tend to be filled with noise-spam from dependabot. It's so bad, that when opening notifications of a day or two, I ctrl-f for dependabot, and unsubscribe from all of them. I don't even look if it's my repo or not (most cases).

I've complained to gh, they seem not to care.

• At the very least, could dependabot's notifications be shoved in to a separate tab in the inbox?
• Alternatively: Ignore dependabot from this repo (should be in the watch dropdown, and then carried over to notifications (repo name, automatically unsubscribe or mark as done).
• Additionally: Make an API request while in notifications (and store the result) to detect, whether it's a repo the user has write access to.
