gatsby-plugin-typescript missing dependency on @babel/core and graphql #20900
Description
Description
gatsby-plugin-typescript (package.json) depends on @babel/plugin-proposal-nullish-coalescing-operator which depends on @babel/core, but gatsby-plugin-typescript doesn't provide that. Under Yarn 2, it's required that gatsby-plugin-typescript has a dependency on @babel/core to satisfy the peer dependency.
There are a few other similar problems, see the Actual result for details.
Steps to reproduce
Using Yarn 2, install gatsby-plugin-typescript:
yarn add gatsby-plugin-typescript
Expected result
