## Problem
We now have `ConnectSheet` and it has been rolled out to everyone.
## Solution
Remove the previous `Connect` components
## Out of scope
There are opportunities to refactor/move the remaining files in the
`apps/studio/components/interfaces/Connect` directory. That will be
addressed in a dedicated PR to ease reviewing.
