Description

We need to change the yellow loading blockaid banner to gray. But right now we don't have a gray color in our design systems, so pending when this is clarified with DS team (ahem @SayaGT) we don't want this to block release, so we will use the info (blue) banner for now.

Manual testing steps

1. Launch MM
2. Perform a PPOM flaggable transaction from testdapp
3. See the yellow banner saying This request is still being simulated......
4. Checkout this branch
5. Repeat 2-4
6. Now see that the same banner is blue
