Add percy/cli to packages to fix percy not found error

[jennifer-shehane]

Percy was not working for some time because the token was missing - fixed here: #1416

For some reason percy is not finding the command/cli to run after that. See CircleCI failure: #1424

Adding percy/cli directly to resolve. This used to use npx, but now we use yarn.
