feat: update suggest group titles

Fix #10550

Demo: https://www.loom.com/share/8f9f18206aad44cba9bf1f3b9580f4fb

To test

• Turn on the Suggest Groups feature
• See that after clicking Suggest Groups, the reflection group title names look good
• Resetting the groups works well too

In the demo, I go through this edge case, which now works well

-1 I think the intention here is: you have 2 groups: group 1 has a smart title and group 2 has only one reflection and a custom title. When we move the one card over to group 1, we want to also apply the custom title to group 1, at least that's happening on master.

I've also updated the prompt and regex to remove Title: as that's coming up frequently for you
