Update Compound and add some new snapshot tests. (#4311)

* Update Compound.

* Add some snapshot tests for PillView on a bubble background.

Version 5.0.0 of compound-design-tokens changed the pill colour but all our snapshots are on white so we didn't notice the difference in contrast. This doesn't fix anything, it purely adds the snapshots.
