feat: enable unsubscribing notifications

[codebytere]

Closes #402.

When the new unsubscribe icon is clicked, all future notifications for a conversation are muted until one comments on the thread or gets an @mention.

Can I suggest that we use the same icon as GitHub? 😉

I feel like it shouldn't be next to "✔" as it's not a primary action so what I did was to place it on the same line with the "reason" and "date" and it's visible only when you hover over a notification. This way we have more space more icons in the future (if needed). Thoughts on the gif? cc @codebytere @JakeSidSmith

[JakeSidSmith]

I wouldn't have it hidden until hover, especially as it will also mark the notification as complete. I imagine people would be likely to click it without meaning to and then struggle to find it again.

[codebytere]

I'd agree with @JakeSidSmith - definitely better to make it a secondary action but perhaps keep it visible by default 🤔

would something like this be fine, or would you prefer the new button to be right-aligned?

[manosim]

Maybe right aligned and always visible would be perfect if you agree? I think we will have to remove it from the list as well - like we do when pressing on the "check"?

@manosim i believe this should be good to go now! Let me know if there are any other tests you'd like me to add, but i covered the basics based on what i saw was already there. The new UI is updated in the main PR body as well, but it looks like this now (the red is on hover):

Amazing - thank you for sorting this out @codebytere ! 🎉
Will give it a couple of days and will cut a new release if nothing else comes up.

@codebytere Can you try pushing an empty commit? It looks like GitHub Actions didn't pick up this PR 😢
