Remove chakra/emotion and unused Storybook components

[KetanReddy]

Chakra (and emotion by extension) are fairly big dependencies that we were pulling in for a single error screen in Storybook. It looks like at some point (potentially during the 6->7 migration) these components stopped being used by Storybook. Long term we should probably try and replicate some of this behavior in our storybook extension but given that it seems like these haven't worked in a while, removing them only has the net benefit of dep reduction.

Closes: #769
