Describe the bug

From the docs page, the order that is used to load the configs should be:

1. a package.json property.
2. a JSON or YAML, extensionless "rc file".
3. a "rc file" with the extensions .json, .yaml, .yml, .toml, .ts or .js.
4. a .config.js CommonJS module, or a .config.ts Typescript module using cosmiconfig-typescript-loader

Instead in the implementation package.json comes after the "rc files": https://github.com/kamilkisiela/graphql-config/blob/523362dbb8bd81cc30838cde6e33f71e6979e7ab/src/helpers/cosmiconfig.ts#LL57-L74C5

To Reproduce

• Create a .graphqlrc.js
• Add a "codegen" section to your "package.json"

Expected behavior

The section inside the "package.json" should take precedence

Environment:

• OS: any
• GraphQL Config Version: latest
• NodeJS: any
