The package @wordpress/reusable-blocks attempts to use @babel/runtime from build/store/index.js and a few other files, but does not declare a dependency or peer dependency on that package.

This happens to work with npm's hoisting due to other dependencies pulling that package in, but will fail with yarn's p'n'p or pnpm with hoisting disabled.

Reproduction

With yarn:

1. Create a temporary directory, and cd into it.
2. echo '{}' > package.json
3. yarn set version stable
4. yarn add @wordpress/reusable-blocks react@^17 react-dom@^17 @babel/core jsdom global-jsdom
5. yarn node -e 'require( "global-jsdom/register" ); const x = require( "@wordpress/reusable-blocks" ); console.log( typeof x );'

With pnpm:

1. Create a temporary directory, and cd into it.
2. echo 'hoist-pattern=[]' > .npmrc
3. pnpm add @wordpress/reusable-blocks react@^17 react-dom@^17 @babel/core jsdom global-jsdom
4. node -e 'require( "global-jsdom/register" ); const x = require( "@wordpress/reusable-blocks" ); console.log( typeof x );'

Actual behavior

With yarn:

Error: @wordpress/reusable-blocks tried to access @babel/runtime, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.
