New icons for AI chat, alarms, and like/dislike; update icon rectangl…

…e-lines. (#2532)

# Pull Request

## 🤨 Rationale

#2530

## 👩‍💻 Implementation

Followed the normal process. Some notes:
1. I renamed the "alarm" icon names suggested in the issue to use "bell"
which aligns better with existing icons and our naming guidance.
2. I removed the color from the bell-radial-lines icon as is our normal
practice

## 🧪 Testing

Verify you can apply severity on the new icons.

## ✅ Checklist

<!--- Review the list and put an x in the boxes that apply or ~~strike
through~~ around items that don't (along with an explanation). -->

- [x] I have updated the project documentation to reflect my changes or
determined no changes are needed.
