Describe the bug

@graphql-tools/graphql-tag-pluck has a dependency on @babel/plugin-syntax-import-assertions. That package has a peer dependency on @babel/core^7.0.0-0. As a result, pnpm is emitting peer dependency warnings due to @babel/core not being present:

└─┬ @graphql-codegen/cli 3.0.0
  └─┬ @graphql-tools/code-file-loader 7.3.21
    └─┬ @graphql-tools/graphql-tag-pluck 7.5.0
      └─┬ @babel/plugin-syntax-import-assertions 7.20.0
        └── ✕ missing peer @babel/core@^7.0.0-0
Peer dependencies that should be installed:
  @babel/core@^7.0.0-0

The dependency for @babel/plugin-syntax-import-assertions was added in #4863. Since that package has a peer dependency on @babel/core, that should be added as well so that consumers without @babel/core do not get peer dependency warnings or an alternative approach devised which makes the syntax transformation opt-in.

To Reproduce
Steps to reproduce the behavior:

Add @graphql-tools/graphql-tag-pluck as a dependency without installing @babel/core. pnpm will emit a peer dependency warning. It's been a while since I've used npm or yarn, but I suspect they would exhibit similar warnings.

Expected behavior

No peer dependency warnings.

Environment:

• OS: Windows
• @graphql-tools/...: See dependency tree in description
• NodeJS: 18.14.0

Yarn warning:

Yarn workaround:

I don't use PNPM or newer versions of Yarn. PRs are welcome to fix it.

https://next.babeljs.io/docs/v8-migration/#babelplugin-syntax-import-assertions

Please migrate to @babel/plugin-syntax-import-attributes (#15536). After you replace the plugin, you should search and replace the following patterns in your codebase:

- import value from "module" assert { type: "json" };
+ import value from "module" with { type: "json" };

Closing this issue since peer dependency has bene added in the latest version.
