Config is not loaded from package.json

[ionut-botizan]

Describe the bug
The default search locations of cosmicconfig are overwritten and the package.json option is left out, so configs are not loaded from it.
The culprit: https://github.com/kamilkisiela/graphql-config/blob/master/src/helpers/cosmiconfig.ts#L71
The original: https://github.com/davidtheclark/cosmiconfig/blob/main/src/index.ts#L109

To Reproduce
Steps to reproduce the behavior:

1. Define a graphql configuration in package.json
2. Try to load it using loadConfigSync

A Codesandbox example where configurations are loaded from .#rc files, #.config.js files, but not from package.json:
https://codesandbox.io/s/graphql-config-ignoring-packagejson-nergw?file=/src/index.js

Expected behavior
The loadConfigSync function should load the graphql configuration from the package.json file, as per the graphql-config documentation and the default behavior of cosmiconfig

Environment:

• OS: All
• GraphQL Config Version: 3.2.0
• NodeJS: All
