Describe the bug

As mentioned in a downstream issue in graphql-codegen it looks like loading cosmiconfig-typescript-loader default export is buggy in esm. The "simple" fix would be to use default-import until this is addressed upstream.

To Reproduce

• fetch local copy of https://github.com/dotansimha/graphql-code-generator/tree/master/examples/typescript-esm
• run npm run codegen

Expected behavior

execution without error

Environment:

• OS: Windows
• NodeJS: 18.4
• graphql version: 16.5
• graphql-config version: 4.3.3

@n1ru4l if I'm still getting an issue like this in 4.3.5 is it probably an esbuild bundling issue? Something I need to mark as external?
