Description

Due to #51545, @wordpress/block-editor now has a transitive peer dependency on @emotion/react. This is unexpected, I'd think it should be like @wordpress/components where the dependency is hidden from the end user.

Step-by-step reproduction instructions

1. In a fresh directory, create .npmrc like

   strict-peer-dependencies=true
   auto-install-peers=false
   

2. Run pnpm add @wordpress/components react react-dom. Ignore the warnings about reakit and react-autosize-textarea. Other than those, observe that it completes successfully.
3. Run pnpm add @wordpress/block-editor react react-dom. Observe it reports an error about "missing peer @emotion/react@^11.0.0-rc.0".

You can see something similar using yarn's PnP.
