When I send a request to the Chat Input we show both a Pause and a Stop.

I am not convinced that Pause button is needed. @connor4312 I know you had a vision for this - can you remind me what's the difference to stop?
I wanted to check in telemetry if users are actually using Pause but looks like we do not report telemetry for it.

My suggestion:

1. Remove Pause action
2. Modify stop icon to something slightly stronger (larger) - attaching what ChatGPT uses as inspiration

fyi @jo-oikawa @roblourens @bpasero
